Overview

The 2020 Labour Party leadership election was the internal contest to replace Jeremy Corbyn as leader of the UK Labour Party. Corbyn announced on 13 December 2019 that he would stand down as leader following the party's poor performance in the December general election, prompting a leadership contest that ran from 21 February to 4 April 2020. The vote used Labour's one-member-one-vote system and took place alongside the party's deputy leadership election, which produced its own winner.

Process and timetable

The contest began with nominations from Labour parliamentarians and affiliated organisations, followed by a period of campaigning among party members, registered supporters and affiliated supporters. Eligible voters cast ranked choices (the Alternative Vote system), allowing second and further preferences to be redistributed if no candidate secured a majority of first-preference votes. The leadership and deputy leadership tallies were declared in early April 2020 after ballots were returned by post and email to qualifying participants.

Candidates and platforms

Several figures declared or sought nominations; the main candidates on the final ballot reflected different currents within the party. Keir Starmer ran on a platform emphasising rebuilding trust, strengthening opposition competence and presenting a credible alternative to the governing party. Rebecca Long-Bailey positioned herself as the continuity-left candidate, advocating many of the policies associated with the previous leadership. Lisa Nandy emphasised reconnecting Labour with communities and traditional strongholds. The contest focused on questions of policy direction, electability and party unity.

Result and immediate aftermath

The contest was won by Keir Starmer, who received a majority of first-preference votes and was declared leader in early April. He set out to reorganise the parliamentary party and reset Labour's public messaging. The deputy leadership election was held concurrently; its result and subsequent appointments shaped the shadow cabinet and Labour's organisational priorities going forward. The outcome marked a clear change in leadership style and signalling toward the wider electorate.

Significance and notable points

  • The election followed Labour's heavy defeat in the December 2019 general election and was widely viewed as a turning point for the party's strategy and positioning.
  • Candidates needed nominations from MPs and endorsements from party sections to reach the ballot, reflecting internal party procedures for leadership contests.
  • The contest coincided with the deputy contest (see details) and occurred as the UK faced other major political and public-policy challenges, giving the new leadership a broad agenda.
