Angela Rayner's dramatic resignation as Labour's deputy leader has prompted a scramble within the party to identify her successor, with a range of frontbenchers and backbenchers already being mooted for the post.
Members and senior figures have said there is pressure on the party to appoint a woman and to select someone from outside London, a dynamic that is shaping early jockeying for position among potential candidates.
Among the names being discussed is Shabana Mahmood, who was appointed Home Secretary last week. Mahmood is viewed as having strong links inside the centre of the party; she served as Labour's national campaign coordinator and has ties to Morgan McSweeney, Sir Keir Starmer's chief of staff. Mahmood, 44, has been MP for Birmingham Ladywood since 2010 and previously worked as a barrister. Her recent move to the Home Office has placed her at the centre of the government's focus on migration and asylum policy, prompting questions about whether she can take on an additional party role while leading a major department.
David Lammy, who was moved in the most recent reshuffle to the post of Deputy Prime Minister after being shifted from Foreign to Justice Secretary, is also considered a potential contender. Lammy, 53, has been MP for Tottenham since 2000 and previously practised as a barrister. He has a long profile within the parliamentary party but has had mixed results in internal selection contests: he finished fourth in Labour's 2015 London mayoral selection race.
Dame Emily Thornberry has said she is "considering" a run. The Islington South and Finsbury MP, 65, who was party shadow attorney general until polling day at last year's election, has delivered public criticism of some aspects of the government's performance and has voiced concerns about Labour's domestic direction. Thornberry was not given a Cabinet role after the election, a decision noted by commentators as she weighs whether to stand.
On the party's left, Richard Burgon has been urged by members and trade unionists to put his name forward. Burgon, 44, MP for Leeds East since 2015 and a former solicitor, served as shadow justice secretary under Jeremy Corbyn and is a member of the Socialist Campaign Group. He has been a vocal critic of the government on welfare cuts and foreign policy. Labour's left has been largely sidelined under Sir Keir's leadership, and observers say Burgon may face challenges securing the level of parliamentary nominations some internal contests require.
Louise Haigh is another figure whose name is being discussed. The 38-year-old MP for Sheffield Heeley, a former trade unionist and special constable, was forced to resign as shadow transport secretary in November after it emerged she had a past guilty plea for fraud. Haigh has strong trade-union links and was recently tipped by Greater Manchester Mayor Andy Burnham. In a recent New Statesman article she called for an "economic reset" and a reassessment of the party's fiscal approach.
Lucy Powell, the MP for Manchester Central since 2012, is also in the frame. Powell was sacked from government in last week's reshuffle when she lost her role as Leader of the House of Commons. A former deputy chief of staff to Ed Miliband, Powell has spent her career working in and around politics and has been presented by some regional figures as a candidate who could give the deputy role a northern voice.
Rosena Allin-Khan, an NHS doctor and MP for Tooting since 2016, finished second to Rayner in the 2020 deputy leadership contest and remains a potential candidate. Allin-Khan has been a frequent critic of aspects of Sir Keir's leadership, particularly on foreign policy matters related to Gaza, and continues to undertake occasional clinical shifts at a hospital in her constituency.
Dawn Butler has called for a "fair process" for choosing Rayner's successor and has hinted at a bid. Butler, 55, MP for Brent since 2005, was a shadow minister under Jeremy Corbyn and served briefly as a junior minister in Gordon Brown's government. She ran in the 2020 deputy leadership contest but was the first candidate eliminated.
The emerging field reflects tensions within Labour between the centre and the left, and between the leadership's desire for unity and calls from some quarters for a deputy who can represent the party's regional and grassroots membership. Sir Keir Starmer's team faces competing pressures: to project stability in government while keeping the party coalition intact.
Candidates and supporters say the contest will be fought on the basis of experience, political vision and ability to hold the government to account. Labour has not announced a timetable for selecting a successor, and those involved say discussions are at an early stage as potential candidates test support among MPs and the wider membership.
How the party resolves the contest will be watched as an indicator of Labour's direction in government and its relationship with activists, trade unions and MPs across its broad ideological range.
