The 2025 Labour Party deputy leadership election was triggered on 5 September 2025 by the resignation of Angela Rayner as deputy leader of the Labour Party. It will be the first deputy leadership election held by Labour in government since the 2007 deputy leadership election.
It is expected that the election will be a contest between a candidate from the left or soft left of the Labour Party and a centrist candidate on the party's right.
The 2020 deputy leadership election resulted in the election of soft left candidate Angela Rayner as deputy leader of the Labour Party, serving under Labour leader Keir Starmer. Following Labour's victory in the 2024 general election, Rayner served as Starmer's deputy prime minister and housing secretary until 5 September 2025, when she resigned after failing to pay stamp duty tax. [1] [2] Rayner also resigned as deputy leader of the Labour Party, triggering an internal leadership election to elect a new deputy leader, in line with the provisions of the Labour Party Constitution. [1] [3] [4]
It is expected that the leadership election will become a contest between a candidate from the left or soft left of the Labour Party, who may try to influence or pressure the more centrist leadership of Prime Minister Keir Starmer towards a more left-wing platform, and a centrist or Blairite candidate on the party's right. [2] [3] [5] The election is expected to overshadow the coinciding period of the Starmer government and has raised concerns of leading to re-emerged factionalism within the party. [6] [3] This has led to comparisons with the 1981 deputy leadership election, which saw the party split after left-wing candidate Tony Benn challenged Denis Healey. [7] [5] [8] It will be the first deputy leadership election held by Labour in government since the 2007 deputy leadership election.
The timeline of the campaign will be decided by the National Executive Committee of the Labour Party (NEC). [3] The constitution of the party states that a deputy leadership election, if triggered while Labour is in government, must be held at the next Labour Party Conference, which is currently scheduled to take place from 28 September to 1 October 2025. [9] [10] Until then, the Labour cabinet can consult the NEC to appoint an interim deputy leader of its choice, or alternatively choose to keep the deputy leadership vacant until party conference. [11] [10] As the election was triggered less than a month before the conference, it has been theorised that the NEC may try to delay the election to a later date. [11] [5] Alternatively, Starmer has reportedly considered reviving a failed proposal by his predecessor Jeremy Corbyn which would abolish the position of deputy leader of the Labour Party. [12]
The NEC decided to meet on 8 September to discuss the election. [13]

Mayor of Greater Manchester Andy Burnham, who is unable to contest the election as he is not an MP, has endorsed the prospective campaigns of either Louise Haigh or Lucy Powell, both of whom are former cabinet ministers sacked by Starmer.

[3] The Conversation suggest that Emily Thornberry, Rosena Allin-Khan and Anneliese Dodds may be candidates. [10] The Guardian offer the following as potential candidates: Shabana Mahmood, Ed Miliband, Emily Thornberry, Wes Streeting, David Lammy, Steve Reed, Bridget Phillipson and Peter Kyle.
