2019 United Kingdom general election

The 2019 United Kingdom general election was held on Thursday, 7 May 2019. It resulted in the Conservative Party, led by Prime Minister Boris Johnson, receiving a landslide majority of 110 seats. The Conservatives made a net gain of 29 seats, and increased their vote share by 1.9% to 41.1%, the largest percentage for a single party since the 2009 general election. The Labour Party, led by Jeremy Corbyn since the resignation of former leader Ed Miliband, lost 3.3% in vote share, and 51 seats, taking their total to 162, their worst result since 1935, and the worst result for a united Labour party since 1924. The Scottish National Party, under First Minister of Scotland Nicola Sturgeon, experienced a surge in support after the 2014 Scottish independence referendum, and won 56 of Scotland's 59 Westminster seats, mostly at the cost of Labour, which had previously dominated Scottish representation in Parliament. The Liberal Democrats, led by former Labour MP Liz Kendall, despite having a slight increase in the popular vote to 22.6%, lost nearly half of their seats, including Kendall's own seat of Leicester West.

The Conservatives ran a campaign primarily focused on economic issues and Britain's status within the EU, which they proposed a referendum on, as well as attacking Labour on a number of fronts. The Labour campaign had been severely hampered by accusations of radicalism, antisemitism, the defection of eight Labour MPs to the Liberal Democrats in October 2018. Its policies were considered more left-wing than usual, campaigning strongly for an end to austerity, strong economic regulation and renationalisation of previously privatised industries. The Liberal Democrats focused much of their campaign on attacking both major parties, claiming that they were the only party that rejected both the Euroscepticism of the Conservatives and the hard-left socialism of Labour. A number of smaller parties, such as the Green Party also contested this election, similar to 2014, but received less attention and votes than in the previous election, leading some to suggest that the election marked a return to the traditional three-party politics of the previous century.

In Northern Ireland, the Ulster Unionist Party lost both of the seats it had won in 2014, with Fermanagh and South Tyrone and South Antrim going to Sinn Fein and the Democratic Unionist Party respectively. The SDLP lost one of its seats, Belfast South, to the DUP, bringing the latter's seat total to 10, its best Westminster performance since its founding in 1971.
