The Labour Party leadership of Jeremy Corbyn began when Jeremy Corbyn was elected as Leader of the UK Labour Party in September 2015, following the resignation of Ed Miliband after Labour's defeat at the 2015 general election. Disillusioned by a lack of a left-wing voice in the 2015 leadership contest, Corbyn stood on an anti-austerity platform. Of the candidates who stood, Corbyn received the fewest parliamentary nominations. Many who nominated him said they had done so not to support his candidacy, but to widen the debate by including a socialist voice. However, Corbyn soon became the frontrunner and was elected with a landslide of 59%. Corbyn appointed John McDonnell as Shadow Chancellor and promoted several female backbenchers, forming a Shadow Cabinet that for the first time had more women than men. Under Corbyn's leadership, Labour shifted to the left from the centre-ground. In November 2015, he voted against British military involvement in the Syrian civil war. He also opposed the renewal of the Trident nuclear weapons system and apologised for the Blair ministry taking the UK into the Iraq War. In spite of his victory, Corbyn enjoyed little support from Labour MPs, although his support remained strong amongst Labour Party members. In 2016, Labour performed poorly at the local and regional elections, and following the European Union membership referendum, in which Britain voted to leave the EU, party opponents accused Corbyn of running a lukewarm campaign for Remain. Several resigned from the Shadow Cabinet and Corbyn lost a motion of no confidence by 197–40. Angela Eagle and Owen Smith launched a formal challenge, although Eagle later withdrew. Corbyn was re-elected with a marginally higher majority of 61%. Although Labour suffered poor results at the local elections in May 2017, at the snap 2017 general election the party secured 40% of the vote with the biggest increase in Labour vote share for 72 years, and forced the Conservatives to form a minority government, with Labour remaining in opposition. In the 2018 local elections, Labour increased its share of the vote. In the 2019 local elections, Labour's seat total dropped by 84. In the 2019 European Parliament election, Labour came third behind the Brexit Party and the Liberal Democrats. In the 2019 general election, Labour's vote share dropped to 32%, winning the lowest number of seats since 1935. The result led to Corbyn's announcement that he would stand down as Labour leader. Some reasons for the defeat included concerns about Corbyn's leadership, the party's "ambiguous" position on Brexit, and concerns that the commitments in the left-wing manifesto were "undeliverable".
