📚 The Importance of Other Parties in the UK | 英国其他政党的重要性
In the United Kingdom, the political landscape has traditionally been described as a two-party system dominated by the Conservative Party and the Labour Party. However, this description overlooks the significant and growing role played by ‘other parties’ such as the Liberal Democrats, the Scottish National Party, the Green Party, Plaid Cymru, and newer movements like Reform UK. At A-Level, understanding the importance of these parties is essential for analysing elections, Parliament, policy-making, and the wider health of representative democracy.
在英国，政治格局传统上被描述为由保守党和工党主导的两党制。然而，这种描述忽视了“其他政党”所发挥的重要且日益增长的作用，例如自由民主党、苏格兰民族党、绿党、威尔士党和更新出现的改革英国党等。在 A-Level 课程中，理解这些政党的重要性对于分析选举、议会、政策制定以及代议制民主的整体健康状况至关重要。
1. Defining ‘Other Parties’ in the UK Party System | 界定英国政党体系中的“其他政党”
In Edexcel Politics, the term ‘other parties’ refers to all registered political parties outside the two largest Westminster parties, the Conservatives and Labour. They range from long-established parties such as the Liberal Democrats and Plaid Cymru to more recent challengers like the Green Party and Reform UK. Although they rarely win a majority of seats in the House of Commons, their influence extends far beyond their seat numbers, especially through votes, campaigns, and coalition politics.
在 Edexcel 政治课程中，“其他政党”一词指的是威斯敏斯特两大政党——保守党和工党——以外的所有注册政党。它们既包括自由民主党、威尔士党等历史悠久的政党，也包括绿党和改革英国党等较新的挑战者。尽管它们很少在下议院赢得多数席位，但其影响力远远超出议席数量，尤其体现在选票、竞选活动和联合政治之中。
These parties can be classified by their ideological position, territorial base, or single-issue focus. For example, the Liberal Democrats are a centrist, pro-European party; the SNP and Plaid Cymru are nationalist parties seeking independence for Scotland and Wales; the Green Party prioritises environmental sustainability; and Reform UK campaigns on immigration control and constitutional change. Recognising this diversity is the first step in assessing their importance.
这些政党可以按意识形态立场、地域基础或单一议题焦点进行分类。例如，自由民主党是一个中间派、亲欧洲的政党；苏格兰民族党和威尔士党是寻求苏格兰和威尔士独立的民族主义政党；绿党优先关注环境可持续性；改革英国党则围绕移民控制和宪法改革开展活动。认识到这种多样性是评估其重要性的第一步。
- Minor parties contest elections but usually win only a small number of seats, while regional parties such as the SNP dominate specific nations, and single-issue parties can shape debate even with limited representation.
- 少数党参加选举但通常只赢得少量席位，而像苏格兰民族党这样的地区性政党可以在特定地区占据主导地位，单一议题政党即使代表人数有限也能影响辩论方向。
2. Electoral System Constraints and Opportunities | 选举制度的限制与机会
The UK’s first-past-the-post electoral system makes it difficult for smaller parties to convert votes into seats. Because the candidate with the most votes in each constituency wins, support that is spread evenly across the country often produces very few MPs. This systematic bias has historically protected the two dominant parties. However, where support is geographically concentrated, as with the SNP in Scotland or Plaid Cymru in Wales, other parties can win substantial numbers of seats and even dominate their region.
英国的简单多数制选举制度使得小党很难将选票转化为席位。由于每个选区中得票最多的候选人获胜，在全国范围内均匀分布的支持往往只能产生极少的议员。这种系统性偏差在历史上保护了两个主导政党。然而，当支持在地理上集中时，例如苏格兰的苏格兰民族党或威尔士的威尔士党，其他政党就能赢得大量席位，甚至主导其所在地区。
The Liberal Democrats have been particularly vocal in calling for proportional representation, arguing that the current system underrepresents their voters. In the 2019 general election, the Liberal Democrats won 11.5% of the vote but only 11 seats, while the SNP won 3.9% of the UK vote but 48 seats because its support was concentrated in Scotland. This contrast illustrates how the importance of other parties is often shaped by the electoral system rather than simply by their national popularity.
自由民主党一直特别积极地呼吁实行比例代表制，认为现行制度未能充分代表其选民。在 2019 年大选中，自由民主党赢得了 11.5% 的选票，却只获得 11 个席位；而苏格兰民族党只赢得英国总选票的 3.9%，却因支持集中在苏格兰而获得 48 个席位。这一对比表明，其他政党的重要性往往受到选举制度的影响，而不仅仅取决于其全国受欢迎程度。
3. Coalition and Confidence-and-Supply Politics | 联合政府与信任供给政治
Perhaps the most direct demonstration of the importance of other parties occurred after the 2010 general election, which produced a hung parliament. The Liberal Democrats, under Nick Clegg, entered a formal coalition with David Cameron’s Conservatives. This gave the Liberal Democrats five Cabinet positions and the ability to negotiate key policies, including a referendum on the Alternative Vote and the introduction of the pupil premium. Coalition politics transformed a minor party into a governing party and showed that other parties can directly exercise executive power.
其他政党重要性最直接的体现或许出现在 2010 年大选之后，那次选举产生了悬浮议会。尼克·克莱格领导下的自由民主党与戴维·卡梅伦领导的保守党组建了正式联合政府。这使得自由民主党获得了五个内阁职位，并能够就关键政策进行谈判，包括就替代投票制举行公投以及引入“学生津贴”。联合政治将一个少数党转变为执政党，表明其他政党可以直接行使行政权力。
Between 2017 and 2019, the Conservative government relied on a confidence-and-supply agreement with the Democratic Unionist Party to maintain a working majority in the House of Commons. In exchange for support on budgets and confidence votes, the DUP secured additional funding for Northern Ireland and influence over Brexit legislation. Such arrangements demonstrate that even parties with few seats can hold the balance of power and shape government survival.
2017 年至 2019 年间，保守党政府依靠与民主统一党的信任供给协议在下议院维持有效多数。作为在预算和信任投票上提供支持的交换，民主统一党为北爱尔兰争取到了额外资金，并对脱欧立法产生了影响。此类安排表明，即使席位较少的政党也能掌握权力平衡，影响政府的存续。
4. Policy Influence Beyond Seats | 席次之外的政策影响力
Other parties often influence policy without entering government. Their campaigns can push major parties to adopt or respond to certain policies. For example, the Green Party has consistently highlighted climate change, and its electoral pressure has encouraged both Labour and the Conservatives to strengthen their environmental commitments. Similarly, UKIP’s success in the 2014 European Parliament elections and its high vote share in 2015 were key factors in David Cameron’s decision to hold the 2016 EU referendum.
其他政党常常无需进入政府就能影响政策。它们的竞选活动可以推动主要政党采纳或回应某些政策。例如，绿党持续强调气候变化问题，其选举压力促使工党和保守党都加强了环保承诺。同样，英国独立党在 2014 年欧洲议会选举中的成功以及 2015 年的高得票率，是卡梅伦决定在 2016 年举行欧盟公投的关键因素。
This agenda-setting role is especially visible with parties that own a particular issue. The SNP owns the issue of Scottish independence, forcing Westminster governments to grant referendums and devolve more powers. The Liberal Democrats own the issue of civil liberties and constitutional reform, keeping those ideas alive even when they are not in office. Thus, measuring importance solely by seats won ignores the wider policy impact of other parties.
这种议程设置作用在拥有特定议题的政党身上尤为明显。苏格兰民族党拥有苏格兰独立这一议题，迫使威斯敏斯特政府批准公投并下放更多权力。自由民主党拥有公民自由和宪法改革议题，即使不在执政期间也能保持这些理念的活力。因此，仅以赢得的席位来衡量重要性，会忽视其他政党更广泛的政策影响。
| Party | 政党 | Issue Owned | 主导议题 | Policy Impact | 政策影响 |
|---|---|---|
| Green Party | 绿党 | Climate change | 气候变化 | Pushed net-zero targets onto main parties | 推动主要政党设定净零目标 |
| UKIP / Reform UK | 英国独立党 / 改革英国党 | EU membership and immigration | 欧盟成员身份与移民 | Led directly to the 2016 Brexit referendum | 直接导致 2016 年脱欧公投 |
| SNP | 苏格兰民族党 | Scottish independence | 苏格兰独立 | Secured two referendums and major devolution | 争取到两次公投和重要权力下放 |
5. Representation of Regional and Nationalist Interests | 地区与民族主义利益的代表
The UK is a union of four nations, and other parties play a vital role in representing the distinct interests of Scotland, Wales, and Northern Ireland. The SNP has been the largest party in Scotland since 2007, winning the vast majority of Scottish seats at Westminster. Its MPs use Question Time, select committees, and parliamentary votes to advance Scottish interests and challenge policies they believe harm Scotland, such as certain post-Brexit trade arrangements.
英国是由四个民族组成的联合王国，其他政党在代表苏格兰、威尔士和北爱尔兰的独特利益方面发挥着至关重要的作用。苏格兰民族党自 2007 年以来一直是苏格兰最大的政党，赢得了苏格兰在威斯敏斯特的绝大多数席位。其议员利用质询时间、专门委员会和议会投票来推进苏格兰的利益，并挑战他们认为损害苏格兰的政策，例如某些脱欧后的贸易安排。
Plaid Cymru performs a similar function for Wales, although on a smaller scale. In Northern Ireland, the main parties are entirely different from those in Great Britain: Sinn Féin, the DUP, and others dominate politics there. Without these ‘other parties’, the voices of the devolved nations would be far weaker in the UK Parliament, and the union itself might face greater instability.
威尔士党为威尔士发挥类似作用，只是规模较小。在北爱尔兰，主要政党与大不列颠完全不同：新芬党、民主统一党等主导着当地政治。如果没有这些“其他政党”，权力下放地区在英国议会中的声音将大大减弱，联合王国本身也可能面临更大的不稳定。
6. Enhancing Political Participation and Voter Choice | 增强政治参与和选民选择
Other parties broaden the range of choices available to voters, which can increase turnout and political engagement. In safe seats where one major party dominates, many citizens feel their vote is wasted. Smaller parties offer an alternative that may align more closely with their values, encouraging people who might otherwise abstain to participate. The Green Party, for example, attracts younger voters and environmental activists who feel unrepresented by the traditional parties.
其他政党扩大了选民可选择的范围，这可以提高投票率和政治参与度。在一个主要政党占主导地位的安全选区，许多公民觉得自己的选票被浪费了。较小的政党提供了更符合他们价值观的替代选择，鼓励那些原本可能弃权的人参与投票。例如，绿党吸引了年轻选民和环保活动人士，他们觉得自己未被传统政党代表。
Furthermore, other parties often introduce fresh ideas and new candidates into politics, challenging the political class and reducing voter apathy. The rise of Reform UK, for instance, has mobilised voters concerned about immigration and the cost of living. Even when such parties do not win many seats, their campaigns can increase the overall level of democratic debate and participation.
此外，其他政党常常为政治注入新思想和新的候选人，挑战政治阶层，减少选民的冷漠情绪。例如，改革英国党的崛起动员了关注移民和生活成本的选民。即使这些政党没有赢得很多席位，它们的竞选活动也能提高民主辩论和参与的整体水平。
7. Devolved Institutions and Local Government | 权力下放机构与地方政府
Outside Westminster, other parties frequently hold power and make policy in devolved assemblies, local councils, and mayoral offices. The SNP has formed the Scottish Government since 2007, controlling health, education, and transport policy for Scotland. Plaid Cymru has been part of Welsh Government coalitions, and the Green Party has held ministerial roles in Scotland and numerous local council seats across England. This sub-national power allows other parties to demonstrate their competence and build a record of governance.
在威斯敏斯特之外，其他政党经常在权力下放议会、地方议会和市长办公室中掌权并制定政策。苏格兰民族党自 2007 年以来一直组建苏格兰政府，控制着苏格兰的卫生、教育和交通政策。威尔士党曾参与威尔士政府的联合执政，绿党在苏格兰担任过部长职务，并在英格兰各地拥有众多地方议席。这种次国家层面的权力使其他政党能够展示其执政能力，并建立治理记录。
The presence of other parties in devolved bodies also contributes to policy diversity across the UK. For example, Scotland has adopted more progressive income tax rates under the SNP than England under the Conservatives, and Wales has introduced different educational reforms under Labour–Plaid Cymru arrangements. These differences highlight how other parties can shape the daily lives of citizens even when they are not in Westminster government.
其他政党在权力下放机构中的存在也促进了英国各地政策的多样性。例如，在苏格兰民族党领导下，苏格兰采用了比保守党领导的英格兰更累进的所得税税率；在工党与威尔士党的合作安排下，威尔士推出了不同的教育改革。这些差异凸显了其他政党即使不在威斯敏斯特政府中，也能影响公民的日常生活。
8. The Role in Referendums and Constitutional Change | 公投与宪法变革中的作用
Other parties have been central to the UK’s major constitutional moments. The SNP campaigned successfully for the 2014 Scottish independence referendum, which resulted in 45% voting to leave the UK. Although the SNP lost that referendum, the campaign fundamentally changed Scottish politics and led to increased devolution through the Scotland Act 2016. The party’s continued strength has kept the question of a second referendum alive.
其他政党在英国的重大宪法时刻中发挥了核心作用。苏格兰民族党成功推动了 2014 年苏格兰独立公投，结果 45% 的人投票支持脱离英国。尽管苏格兰民族党在那次公投中失利，但这场运动从根本上改变了苏格兰政治，并通过《2016 年苏格兰法案》推动了更多权力下放。该党的持续强势使第二次公投的问题一直存在。
Similarly, UKIP’s pressure led to the 2016 EU membership referendum, and the Liberal Democrats campaigned for a referendum on the Alternative Vote in 2011. More recently, other parties have advocated for reforming the House of Lords, introducing proportional representation, and establishing a written constitution. These constitutional issues may not always reach the statute book, but they keep reform on the political agenda and force larger parties to respond.
同样，英国独立党的压力促成了 2016 年欧盟成员身份公投，自由民主党则在 2011 年推动了替代投票制公投。近年来，其他政党还主张改革上议院、引入比例代表制以及制定成文宪法。这些宪法议题不一定总能成为法律，但它们使改革保持在政治议程上，并迫使大党作出回应。
9. Holding Government to Account | 对政府的问责作用
In a two-party system, the largest opposition party usually provides the main challenge to the government. However, other parties also contribute to scrutiny and accountability by using parliamentary procedures, asking questions, and joining select committees. Their MPs often bring specialist knowledge and represent constituencies that the main parties may overlook. This strengthens the overall function of Parliament as a check on executive power.
在两党制中，最大的反对党通常构成对政府的主要挑战。然而，其他政党也通过运用议会程序、提出质询和参加专门委员会，为审查和问责作出贡献。他们的议员往往具有专业知识，并代表主要政党可能忽视的选区。这加强了议会作为行政权力制衡机制的整体功能。
For example, SNP MPs have used Westminster debates to challenge the UK government on issues such as the cost-of-living crisis, welfare cuts, and the impact of Brexit on Scotland. Liberal Democrat and Green peers in the House of Lords have also played a role in amending legislation and defending civil liberties. Even a small number of determined MPs can force the government to justify its decisions and occasionally secure U-turns.
例如，苏格兰民族党议员利用威斯敏斯特辩论，在生活成本危机、福利削减以及脱欧对苏格兰的影响等问题上挑战英国政府。自由民主党和绿党在上议院的议员也在修改立法和维护公民自由方面发挥了作用。即使少数坚定的议员也能迫使政府为其决策辩护，有时还能促成政策转变。
10. Barriers to Influence and their Limits | 影响力的障碍及其局限
Despite their importance, other parties face significant barriers. The first-past-the-post system, limited media coverage, and unequal funding all reduce their ability to compete fairly. The mainstream media tends to focus on the Conservative and Labour leaders, which makes it harder for smaller parties to communicate their messages. During general elections, broadcasters often invite only the leaders of the three largest parties to televised debates, reinforcing the two-party image.
尽管其他政党很重要，但它们面临着重大障碍。简单多数制、媒体报道有限以及资金不平等等因素都削弱了它们公平竞争的能力。主流媒体往往聚焦于保守党和工党的领导人，这使得小党更难传达自己的信息。在大选期间，广播机构通常只邀请三个最大政党的领导人参加电视辩论，这强化了两党制的形象。
Moreover, other parties can suffer from the perception that a vote for them is a wasted vote, leading to tactical voting. Their influence often depends on the specific circumstances of a hung parliament or a regional concentration of support. When one major party wins a large majority, the importance of other parties in Westminster is greatly reduced, though it may persist in devolved bodies and local government.
此外，其他政党还可能受到“投它们就是浪费选票”这一观念的影响，导致策略性投票。它们的影响力往往取决于悬浮议会或地区性支持集中的特定情况。当一个主要政党赢得大量多数席位时，其他政党在威斯敏斯特的重要性就会大大降低，尽管这种重要性在权力下放机构和地方政府中可能仍然存在。
11. Case Studies: Liberal Democrats, SNP, and Reform UK | 案例研究：自由民主党、苏格兰民族党和改革英国党
The Liberal Democrats demonstrate the double-edged nature of being an ‘other party’. In coalition from 2010 to 2015, they achieved real policy wins, including raising the income tax threshold and delivering a referendum on electoral reform. However, their decision to break a pledge on tuition fees led to a collapse in support, showing that smaller parties can be punished severely for compromises made in government.
自由民主党展示了作为“其他政党”的双刃剑性质。在 2010 至 2015 年的联合政府中，他们取得了实际的政策胜利，包括提高个人所得税起征点和就选举改革举行公投。然而，他们违背学费承诺的决定导致支持率暴跌，这表明小党可能因在政府中作出的妥协而受到严厉惩罚。
The SNP illustrates how a regional party can dominate a nation and shape the constitutional agenda. By winning almost every Scottish Westminster seat in 2015 and 2019, the SNP gave Scotland a powerful voice and kept independence at the centre of UK politics. However, internal divisions and policy controversies have shown that even dominant ‘other parties’ face challenges in maintaining unity and public trust.
苏格兰民族党展示了一个地区性政党如何主导一个民族并塑造宪法议程。通过在 2015 年和 2019 年赢得几乎所有的苏格兰威斯敏斯特席位，苏格兰民族党为苏格兰提供了强有力的声音，并使独立问题始终处于英国政治的中心。然而，内部分歧和政策争议表明，即使是占主导地位的“其他政党”在维护团结和公众信任方面也面临挑战。
Reform UK, formerly the Brexit Party, shows how a new party can disrupt politics without winning seats. By campaigning on immigration and criticising the political establishment, it has forced the Conservatives to adopt tougher rhetoric and policies. Its growing vote share in 2024 suggests that ‘other parties’ can rapidly change the political landscape and split the right-wing vote, affecting seat outcomes under first-past-the-post.
改革英国党（前身为脱欧党）展示了新政党如何在没有赢得席位的情况下扰乱政治。通过围绕移民问题开展竞选并批评政治建制，它迫使保守党采取了更强硬的言辞和政策。它在 2024 年不断增长的得票率表明，“其他政党”能够迅速改变政治格局并分裂右翼选票，从而在简单多数制下影响席位结果。
12. Conclusion: Evaluating their Overall Importance | 结论：评估其总体重要性
The importance of other parties in the UK cannot be measured by parliamentary seats alone. They act as coalition partners, policy entrepreneurs, regional representatives, constitutional reformers, and accountability mechanisms. In a two-party dominant system, they are often the main source of pressure for change, forcing the Conservatives and Labour to respond to new issues and shifts in public opinion.
英国其他政党的重要性不能仅仅通过议会席位来衡量。它们充当联合政府伙伴、政策推动者、地区代表、宪法改革者和问责机制。在两党主导的体系中，它们往往是变革压力的主要来源，迫使保守党和工党对新议题和舆论变化作出回应。
At the same time, their influence is conditional and uneven. The first-past-the-post system, media bias, and tactical voting limit their parliamentary presence, but devolution, hung parliaments, and issue ownership can give them power far beyond their size. For any student of UK politics, ignoring other parties means missing a crucial dimension of how the British political system actually operates.
与此同时，它们的影响力是有条件的、不均衡的。简单多数制、媒体偏见和策略性投票限制了它们在议会的存在，但权力下放、悬浮议会和议题主导权可以赋予它们远超过其规模的力量。对于任何学习英国政治的学生来说，忽视其他政党就意味着错过了英国政治体系实际运作的一个关键维度。
