1. Defining Political Parties | 政党的定义

A political party is an organised group of people with similar political aims and opinions, seeking to influence public policy by getting its candidates elected to public office. Parties typically present a manifesto outlining their policies before a general election. They differ from pressure groups in that they aim to exercise power directly rather than merely influence those in power. In the UK, parties are registered with the Electoral Commission and must comply with rules on funding, candidate selection, and campaigning.

政党是一群具有相似政治目标和观点的人组织起来的团体，通过让其候选人当选公职来影响公共政策。政党通常在大选前发表宣言，概述其政策。政党与压力集团的区别在于政党旨在直接行使权力，而非仅仅影响掌权者。在英国，政党需在选举委员会注册，并遵守有关资金、候选人选拔和竞选活动的规则。

The term “party” derives from the Latin word “partire,” meaning to divide, reflecting the fact that parties represent distinct sections of society. Over time, parties have evolved from loose parliamentary factions in the 18th century into mass-membership organisations with formal structures, constitutions, and regional branches. Today, the main UK parties have sophisticated campaign machines and professional staff, though membership levels have fallen dramatically since the mid-20th century.

“party”一词源自拉丁语”partire”，意为分割，这反映了政党代表社会不同部分的特质。随着时间推移，政党从18世纪松散的议会派系演变为拥有正式结构、章程和地区支部的大规模成员组织。如今，英国主要政党拥有先进的竞选机器和专业工作人员，尽管自20世纪中期以来党员人数已大幅下降。

2. Functions of Political Parties | 政党的功能

Political parties perform several vital functions within a democracy. First, they aggregate and articulate interests by gathering a wide range of demands from individuals and groups and synthesising them into coherent policy programmes. Second, they serve as a mechanism for political recruitment, identifying potential candidates for office and training future leaders. Third, parties formulate policy and draft manifestos that are presented to the electorate, enabling voters to make informed choices.

政党在民主制度中发挥多种重要功能。第一，它们聚合与表达利益，即收集个人和群体提出的广泛需求，并将其综合为连贯的政策纲领。第二，政党是政治录用的机制，发现潜在的候选人并培养未来领袖。第三，政党制定政策并起草选举宣言，提交给选民，使选民能够做出明智的选择。

Parties also perform a representative function: they act as a bridge between citizens and the state, channeling popular concerns into the legislative process. Furthermore, parties are essential for organising government. The party that wins a majority in the House of Commons forms the government, and its MPs provide the personnel for the executive branch. The largest opposition party forms the Official Opposition, which scrutinises the government and presents itself as an alternative government-in-waiting. Finally, parties facilitate participation by encouraging citizens to join, donate, and campaign, thereby strengthening democratic engagement.

政党还承担代表功能：它们充当公民与国家之间的桥梁，将公众关切引入立法程序。此外，政党对组织政府至关重要。在下议院赢得多数席位的政党组建政府，其议员为行政部门提供人员。最大的反对党组成官方反对党，负责监督政府，并将自身塑造为等待上台的替代政府。最后，政党通过鼓励公民加入、捐款和参与竞选活动来促进政治参与，从而加强民主互动。

3. Party Ideologies and Internal Factions | 政党意识形态与内部派系

Each major political party is associated with a core ideology, though internal factions often compete for dominance. The Conservative Party is traditionally associated with conservatism, emphasising order, authority, tradition, and the preservation of established institutions. However, the party has hosted different strands, from One-Nation Conservatism with a paternalistic concern for the poor, to Thatcherism with its focus on free markets and individual responsibility, to post-2016 populist nationalism as seen with the “Get Brexit Done” message.

每个主要政党都与一种核心意识形态相联系，尽管内部派系常常争夺主导地位。保守党传统上与保守主义相关联，强调秩序、权威、传统和维护既有制度。然而，该党内部存在不同派系，从对穷人抱有家长式关怀的一国保守主义，到注重自由市场和个人责任的撒切尔主义，再到2016年后以“搞定脱欧”为代表的民粹民族主义。

The Labour Party was founded on socialist principles and has historically been linked to trade unions. The originally socialist Clause IV, committing the party to common ownership of the means of production, was rewritten in 1995 under Tony Blair, reflecting a shift towards the centre-left ‘Third Way’ and social democracy. More recently, Jeremy Corbyn’s leadership (2015–2020) represented a return to left-wing democratic socialism, while Sir Keir Starmer has steered the party back towards the centre. The Liberal Democrats advocate liberalism and social liberalism, combining a belief in individual freedom with support for state intervention to tackle inequality. Smaller parties such as the Green Party promote ecologism, while the SNP and Plaid Cymru blend nationalism with social democratic policies.

工党成立于社会主义原则之上，历史上与工会相联系。原初的社会主义条款第四条承诺使生产资料公有化，该条款于1995年在托尼·布莱尔领导下被重写，反映了向中左“第三条道路”和社会民主主义的转变。更近期的，杰里米·科尔宾的领导（2015–2020年）代表向左翼民主社会主义的回归，而基尔·斯塔默爵士已将党拉回中间路线。自由民主党倡导自由主义和社会自由主义，将对个人自由的信仰与支持国家干预以解决不平等相结合。绿党等较小政党推广生态主义，而苏格兰民族党（SNP）和威尔士党（Plaid Cymru）则将民族主义与社会民主政策相融合。

4. The Conservative Party: History and Ideology | 保守党：历史与意识形态

The Conservative Party has dominated British politics for much of its history and is often described as the most successful political party in the democratic world. Emerging from the Tory faction in the late 17th century, the modern Conservative Party was founded in 1834. Its ideology has been remarkably flexible, adapting to changing circumstances while preserving core principles of pragmatism, patriotism, and a preference for gradual change.

保守党在其大部分历史中主导了英国政治，常被称为民主世界中最成功的政党。现代保守党发端于17世纪晚期的托利派系，于1834年正式成立。其意识形态极为灵活，能适应变化的环境，同时保持务实主义、爱国主义和渐进变革的核心原则。

One-Nation Conservatism, associated with Benjamin Disraeli and later with figures like Harold Macmillan, emphasises the obligation of the rich to assist the poor, social cohesion, and intervention to maintain stability. In the 1980s, Margaret Thatcher’s radical ‘New Right’ conservatism prioritised privatisation, deregulation, curbing trade union power, and reducing the state’s role. After 2010, David Cameron attempted to modernise the party with a Big Society agenda and compassionate conservatism, though Brexit subsequently fractured the party into pro-European and Eurosceptic wings. The leadership of Boris Johnson and Liz Truss demonstrated ongoing tensions between limited-government libertarianism and populist nationalism. The party’s ability to manage ideological conflict remains a key electoral factor.

与本杰明·迪斯雷利及后来哈罗德·麦克米伦等人相关的一国保守主义，强调富人有义务帮助穷人、社会凝聚力和为维持稳定而干预。在1980年代，玛格丽特·撒切尔的激进“新右派”保守主义优先考虑私有化、放松管制、约束工会权力和缩小国家作用。2010年后，戴维·卡梅伦试图以“大社会”议程和富有同情心的保守主义来实现党的现代化，尽管英国脱欧随后将党分裂为亲欧派和疑欧派。鲍里斯·约翰逊和利兹·特拉斯的领导展示了有限政府自由意志主义与民粹民族主义之间持续存在的紧张关系。该党管控意识形态冲突的能力仍是一个关键的选举因素。

A simple comparison of Conservative factions can be illustrated in the table below:

Faction	Key Beliefs	Key Figures
One-Nation	Paternalism, welfare, social stability	Disraeli, Macmillan
Thatcherite/New Right	Free market, limited state, individualism	Thatcher, Lawson
Modernising/Cameroon	Social liberalism, green agenda	Cameron, May
Populist Nationalist	Brexit sovereignty, cultural conservatism	Johnson, Farage-influence

上表简要比较了保守党内部派系的关键信念与代表人物：一国派强调家长制、福利和社会稳定，撒切尔主义或新右派关注自由市场与有限国家，现代化派倾向社会自由主义与绿色议题，而民粹民族主义派则聚焦脱欧主权与文化保守主义。这些派系之间的角力常常决定党的政策方向。

5. The Labour Party: Evolution and Factions | 工党：演变与派系

The Labour Party was founded in 1900 as the political arm of the trade union movement and rapidly displaced the Liberal Party as the main alternative to the Conservatives. Labour’s constitution originally contained Clause IV, committing the party to public ownership of key industries. The post-war Attlee government (1945–1951) established the NHS and the modern welfare state, embedding social democracy in British politics. However, electoral defeats in the 1980s prompted a fundamental ideological reassessment.

工党于1900年作为工会运动的政治臂膀成立，并迅速取代自由党成为保守党的主要替代者。工党党章最初包含第四条，承诺党将关键产业公有化。战后的艾德礼政府（1945–1951年）建立了国民医疗服务体系和现代福利国家，使社会民主主义嵌入英国政治。然而，1980年代的选举失败促使一次根本性的意识形态重估。

Under Neil Kinnock, John Smith, and especially Tony Blair, the party moved towards the centre. Blair’s New Labour project embraced market economics, constitutional reform, and a tough stance on law and order, while dropping Clause IV in 1995. Critics on the left accused New Labour of abandoning its socialist roots. The financial crisis of 2008 and the Iraq War weakened the party’s credibility. The election of Jeremy Corbyn as leader in 2015 signalled a sharp leftward shift, proposing nationalisation, higher public spending, and unilateral nuclear disarmament – a platform labelled by some as the ‘new politics’. Labour’s heavy defeat in 2019 under Corbyn led to a further revision under Keir Starmer, who has suspended Corbyn from the parliamentary party and emphasised fiscal responsibility. Internal Labour factions thus demonstrate the ongoing struggle between social democratic centrists and more radical socialists.

在尼尔·金诺克、约翰·史密斯，尤其是托尼·布莱尔的领导下，党向中间路线移动。布莱尔的新工党计划拥抱市场经济、宪政改革和严厉的法律与秩序立场，同时于1995年放弃了第四条。左翼批评者指责新工党背弃了社会主义根基。2008年金融危机和伊拉克战争削弱了党的信誉。2015年杰里米·科尔宾当选领导人标志着一次急剧的左转，提出国有化、提高公共支出和单方面核裁军，这一纲领被一些人称为“新政治”。工党在2019年科尔宾领导下遭遇的严重失败后，基尔·斯塔默推动了进一步路线修正，他将科尔宾停职出党并强调财政责任。因此，工党内部的派系斗争展示了社会民主主义的中间派与更激进的社会主义者之间持续的斗争。

Key ideological turns within Labour can be tracked as follows: from the social democracy of Attlee, through the centre-left Third Way of Blair, to the democratic socialism of Corbyn, and now to Starmer’s cautious centrism. This evolution is essential to understanding the party’s shifting electoral appeal and policy platforms.

工党内部关键意识形态转向可追踪如下：从艾德礼的社会民主主义，经过布莱尔的中左第三条道路，到科尔宾的民主社会主义，再到如今斯塔默谨慎的中间主义。理解这一演变对于把握该党不断变化的选举吸引力和政策纲领至关重要。

6. The Liberal Democrats and Minor Parties | 自由民主党与小党

The Liberal Democrats were formed in 1988 from a merger of the Liberal Party and the Social Democratic Party (SDP). The party positions itself as a progressive, centrist alternative to the two larger parties, championing civil liberties, electoral reform, and environmental issues. Historically, the Liberals were one of the two main parties until the rise of Labour in the early 20th century. The Liberal Democrats achieved their best modern result in 2005, winning 62 seats, and entered a coalition government with the Conservatives in 2010. However, their support for raising tuition fees led to a dramatic collapse in popularity, and they lost most of their seats in 2015.

自由民主党于1988年由自由党和社会民主党（SDP）合并而成。该党定位为两大党之外的进步、中间派的替代选择，倡导公民自由、选举改革和环境议题。历史上，自由党曾是两大主要政党之一，直到20世纪初工党崛起。自由民主党在2005年取得现代最佳成绩，赢得62个席位，并于2010年与保守党组成联合政府。然而，他们支持提高大学学费导致声望急剧下降，2015年失去了大部分席位。

Under leaders such as Tim Farron, Vince Cable, and Jo Swinson, the party tried to regain momentum by emphasising its pro-European stance, particularly around Brexit. Their call for a second referendum attracted a segment of Remain voters, but the 2019 election saw them reduced to just 11 seats. Despite this, they remain the largest third party in English seats at Westminster. Other minor parties include the Green Party of England and Wales, which focuses on environmental sustainability, social justice, and pacifism. The Greens hold only one seat in the Commons but have influence in local government and London Assembly. UKIP (the UK Independence Party), which was instrumental in forcing the EU referendum, has declined sharply since 2016 but still represents a Eurosceptic legacy. The Brexit Party, rebranded as Reform UK, continues to advocate populist, anti-immigration themes. The existence of multiple minor parties enriches political debate but reveals the structural limits of the First Past the Post electoral system in translating votes into seats.

在蒂姆·法伦、文斯·凯布尔和乔·斯温森等领导人的带领下，该党试图通过强调其亲欧盟立场，尤其是在脱欧问题上，来重振声势。他们呼吁二次公投吸引了一部分留欧选民，但2019年大选使该党席位减少至仅11席。尽管如此，自由民主党仍然是威斯敏斯特英格兰选区中最大的第三党。其他小党包括英格兰和威尔士绿党，该党专注于环境可持续性、社会正义和和平主义。绿党在下议院仅有一个席位，但在地方政府和伦敦议会中具有影响力。英国独立党（UKIP）曾对促成脱欧公投起到了关键作用，自2016年以来已急剧衰落，但仍代表了疑欧派的残留影响。脱欧党更名为改革英国党，继续倡导民粹主义和反移民主题。众多小党的存在丰富了政治辩论，但也揭示了简单多数当选制在将选票转化为席位方面的结构性局限。

7. Party Systems in the UK: Two-Party Dominance? | 英国的政党制度：两党主导？

Britain is often described as having a two-party system, because from 1945 to 1970 the Conservatives and Labour regularly won over 90% of the vote share combined, and single-party majority governments were the norm. Duverger’s law holds that the First Past the Post electoral system tends to produce a two-party system by discouraging votes for smaller parties and penalising them in seat allocation. However, this traditional picture has been challenged since the 1970s.

英国常被描述为拥有两党制，因为从1945年到1970年，保守党和工党合计通常赢得超过90%的选票份额，且一党多数政府是常态。迪韦尔热定律认为，简单多数当选制通过阻止选民选择小党并使其在席位分配中处于劣势，从而倾向于产生两党制。然而，自1970年代以来，这一传统图景受到了挑战。

The February 1974 election resulted in a hung Parliament, and since then hung Parliaments have become more frequent (2010, 2017). The 1980s saw the rise of the SDP-Liberal Alliance, which won over 25% of the vote but only a fraction of seats. The SNP’s surge in Scotland since 2015 has shattered Labour’s former dominance there, while the Brexit realignment fuelled tactical voting and multi-party competition in many constituencies. Some now argue that the UK has a dominant-party system where one party has a significant advantage in resources and support, but this too is contested. The 2019 election returned a large Conservative majority, but the 2024 election could see further realignment. Political scientists therefore tend to characterise the modern UK as a modified two-party system, or a two-and-a-half party system, reflecting the persistent presence of the Liberal Democrats and regional parties. The system’s disproportionality remains high, making it difficult for new parties to break through without a geographical concentration of support.

1974年2月大选出现悬浮议会，此后悬浮议会变得更为频繁（2010年、2017年）。1980年代社会民主党-自由党联盟的崛起，赢得了超过25%的选票但仅获得零星的席位。2015年以来苏格兰民族党（SNP）在苏格兰的崛起摧毁了工党原有的主导地位，而脱欧重组则激发了许多选区的策略性投票和多党竞争。有观点认为英国呈现主导党制，即一个政党在资源和支持上拥有显著优势，但这同样存在争议。2019年大选使保守党获得巨大多数，但2024年选举可能见证进一步重组。因此，政治学家倾向于将当代英国描述为修正的两党制，或两个半政党体系，反映出自由民主党及地区政党持续存在的状态。该制度的不成比例性依然很高，新政党若没有地域集中的支持，就很难取得突破。

8. The Impact of Regional and Nationalist Parties | 地区性与民族主义政党的影响

Nationalist and regional parties wield disproportionate influence in devolved areas and can be pivotal in the House of Commons when no party wins an overall majority. The Scottish National Party (SNP) campaigns for Scottish independence and has governed Scotland since 2007. Following the 2014 independence referendum, the SNP experienced a membership boom and went on to win 56 of Scotland’s 59 seats in 2015, turning Scottish politics into essentially a one-party system at Westminster. Although its seat total dropped to 48 in 2019, the SNP remains a powerful voice for Scotland’s interests and frequently uses its platform to demand a second independence referendum.

民族主义和地区性政党在权力下放地区发挥着不成比例的影响力，并在没有任何政党赢得绝对多数时可能在下议院中成为关键力量。苏格兰民族党（SNP）致力于苏格兰独立，自2007年以来一直治理苏格兰。2014年独立公投后，SNP经历了党员人数的激增，并在2015年赢得了苏格兰59个席位中的56个，使苏格兰政治在威斯敏斯特基本上成为一党制。尽管2019年其席位总数降至48席，但SNP仍然是苏格兰利益的强有力代言者，并经常利用其平台要求举行第二次独立公投。

Plaid Cymru, the Party of Wales, also advocates for Welsh independence and the promotion of the Welsh language. It has consistently held a small number of seats, typically 3–4, in Welsh-speaking heartlands and often cooperates with the SNP on constitutional issues. In Northern Ireland, the party system is entirely different: the main divide is between unionist parties (Democratic Unionist Party – DUP, and Ulster Unionist Party – UUP) that favour remaining part of the UK, and nationalist parties (Sinn Féin and the SDLP) that advocate for a united Ireland. Sinn Féin’s policy of abstentionism means its MPs refuse to take their seats at Westminster, affecting voting arithmetic. The DUP’s 10 MPs after the 2017 election held the balance of power, securing a confidence-and-supply agreement with the Conservatives. These regional dynamics highlight how territorial politics can shape outcomes at UK level, adding layers of complexity to the party system.

威尔士党（Plaid Cymru）同样倡导威尔士独立并推广威尔士语言。它在威尔士语核心地带一贯保有几个席位，通常为3至4席，并经常与SNP在宪制问题上合作。在北爱尔兰，党制则完全不同：主要的分歧在于希望留在英国的联合主义政党（民主统一党DUP和阿尔斯特统一党UUP）与主张统一爱尔兰的民族主义政党（新芬党和社会民主工党SDLP）之间。新芬党的弃权主义政策意味着其议员拒绝在威斯敏斯特就座，从而影响投票算术。2017年大选后，DUP的10名议员掌握了权力平衡，与保守党达成信任与供应协议。这些地区态势凸显了领土政治如何塑造英国层面的结果，为政党制度增加了复杂性。

9. Party Funding: Controversies and Reform | 政党资金：争议与改革

Funding of political parties is a perennial source of controversy in UK politics. The main sources of party income include membership subscriptions, donations from individuals and companies, and, in Labour’s case, trade union affiliation fees. The Political Parties, Elections and Referendums Act 2000 (PPERA) imposed transparency requirements on donations exceeding a certain threshold and set limits on campaign spending. However, the system has repeatedly been criticised for enabling ‘cash for honours’ and for leaving parties dependent on wealthy donors, thus creating perceptions of undue influence.

政党资金是英国政治中一个常年的争议来源。政党的主要收入来源包括党员订阅、个人和公司捐款，以及工党的工会会员费。2000年《政党、选举和全民公投法》（PPERA）对超过一定门槛的捐款规定了透明要求，并对竞选支出设定了限制。然而，这一体系因可能促成“金钱换爵位”并使政党依赖富裕捐赠者而反复受到批评，从而产生了不当影响的观感。

The Labour Party traditionally relies heavily on trade union funding, which links its policy platform to union interests. The Conservative Party benefits from large donations from wealthy individuals and businesses, leading to accusations that its policies favour those donors. The 2009 ‘cash for influence’ scandal, in which peers were allegedly offered in exchange for donations, sparked calls for reform. Various committees, including the Committee on Standards in Public Life, have recommended a system of state funding for political parties, modelled partly on arrangements in countries like Germany or Sweden. However, public opposition to politicians using taxpayers’ money, combined with disagreement on how to distribute funds, has prevented major reforms. As a result, the UK’s funding regime continues to be seen as one of the least transparent in Western Europe. A-level students should weigh the arguments for and against state funding: supporters say it would reduce corruption and level the playing field, while opponents argue it would entrench established parties and waste public money.

工党在传统上严重依赖工会资金，这使其政策纲领与工会利益相挂钩。保守党则从富裕个人和企业的大额捐款中获益，招致其政策偏袒这些捐助者的指责。2009年“以影响换现金”丑闻（指据称以捐款换取上议院席位）引发了改革呼声。包括公共生活标准委员会在内的多个委员会建议建立某种程度的国家资助政党制度，部分借鉴德国或瑞典等国的安排。然而，公众对政客使用纳税人资金的反对情绪，加上各方对资金分配方式的分歧，阻碍了重大改革。因此，英国的资助制度仍被视为西欧最不透明的制度之一。A-level学生应权衡支持与反对国家资助的论据：支持者认为这将减少腐败并使竞争环境更为公平，反对者则认为这将巩固现有政党并浪费公共资金。

10. Party Membership and Future Challenges | 政党成员与未来挑战

Party membership in the UK has fallen dramatically since its peak in the 1950s. In 1953, the Conservative Party had around 2.8 million members, and Labour had over 1 million. Today,
