United Kingdom general election, 2015 The United Kingdom general election held on 7 May 2015 elected 650 Members of Parliament to the House of Commons of the United Kingdom. The contest followed the five-year parliament resulting from the United Kingdom general election, 2010 and produced an unexpected parliamentary outcome that reshaped party leaderships, regional politics in Scotland, and the course of European Union relations. Major political figures at the time included David Cameron, Ed Miliband, Nick Clegg, Nigel Farage, and Nicola Sturgeon.
Background
The election was precipitated by the fixed-term provisions of the Fixed-term Parliaments Act 2011 that set the date for a five-year interval after the United Kingdom general election, 2010, when a Conservative–Liberal Democrat coalition under David Cameron and Nick Clegg governed. Key contextual issues included the aftermath of the 2008 financial crisis, austerity policies advanced by the Conservatives, opposition critiques from the Labour Party under Ed Miliband, and debates about the United Kingdom's relationship with the European Union. Regional dynamics were influenced by the 2014 Scottish independence referendum, leading to a surge for the SNP under Nicola Sturgeon in Scotland and affecting strategic calculations for the Liberal Democrats after their coalition participation.
Electoral System and Dates
The election used the First-past-the-post plurality system across 650 single-member constituencies established under Parliamentary Constituencies Act 1986 provisions and subsequent boundary practices. The franchise followed eligibility rules from the Representation of the People Act 1983, with registered electors resident in the United Kingdom and qualifying Commonwealth and Irish citizens able to vote. Polling took place on 7 May 2015, coinciding with local elections in England and elections for devolved bodies such as the Welsh Assembly and local authorities, while the Electoral Commission oversaw administration and regulation.
Parties and Campaigns
Major parties competing included the Conservatives led by David Cameron, the Labour Party led by Ed Miliband, the Liberal Democrats led by Nick Clegg, and the UK Independence Party led by Nigel Farage. Regional parties included the SNP under Nicola Sturgeon, the Plaid Cymru led by Leanne Wood, the Democratic Unionist Party led by Peter Robinson (with changing leadership dynamics), the Sinn Féin leadership in Northern Ireland, and the Social Democratic and Labour Party under Alasdair McDonnell. Campaign themes invoked policy disputes over NHS funding controversies, welfare reform under the Welfare Reform Act 2012, taxation and fiscal targets, immigration and border controls, and the prospect of a EU referendum which David Cameron promised to negotiate. High-profile events included televised debates moderated by broadcasters like ITV and BBC that featured leaders' confrontations and moments involving Nick Clegg and Nigel Farage.
Opinion Polling and Predictions
Opinion polling throughout the campaign showed fluctuating support: some national polls indicated a Conservative lead, others suggested a close race with Labour, while regional polling in Scotland signalled dramatic gains for the SNP. Psephologists and institutions such as YouGov, Ipsos MORI, and ComRes provided constituency-level modelling used by analysts including Niall Dickson-style commentators and forecasting groups. Many forecasts underestimated the regional concentration effects under First-past-the-post that benefitted the Conservatives and SNP; media projections in outlets like The Guardian and The Daily Telegraph varied, and some academic commentators compared outcomes to similar upset results in parliamentary systems such as the Canadian federal election, 2011.
Results
The Conservatives won 330 seats, achieving an overall majority of one seat over the 326 threshold, with David Cameron positioned to form a majority administration. The Labour Party took 232 seats, while the SNP won 56 of 59 Scottish seats, a landslide that displaced many Labour incumbents including prominent figures. The Liberal Democrats suffered substantial losses, reduced to 8 seats from their previous 57, precipitating leadership change. UK Independence Party secured a notable share of the national vote but returned only one seat, illustrating the disparity between vote share and constituency wins under First-past-the-post. Turnout was approximately 66.1%, with regional variances across England, Scotland, Wales, and Northern Ireland.
Aftermath and Government Formation
Following the result, David Cameron formed a Conservative majority government, ending the Conservative–Liberal Democrat coalition. The outcome prompted leadership resignations including Nick Clegg and Ed Miliband; Ed Miliband's resignation led to a Labour leadership election won later by Jeremy Corbyn. The SNP surge accelerated debates in Holyrood and national discussions over Scottish independence and representation at Westminster, involving Nicola Sturgeon and the Scottish Parliament. The election also amplified calls for electoral reform by groups such as Electoral Reform Society, intensified preparations for the United Kingdom European Union membership referendum, 2016 promised by David Cameron, and triggered strategic reassessments by parties including Plaid Cymru and Democratic Unionist Party. The 2015 result thus previewed major constitutional and party-political shifts in subsequent years.
