Education Secretary Bridget Phillipson has entered the contest to be Labour’s deputy leader, becoming the most senior figure to put her name forward so far.
Bell Ribeiro-Addy, MP for Clapham and Brixton Hill, is so far the only other declared candidate in the race to replace Angela Rayner in the deputy leader role.
Chair of the Foreign Affairs Committee Emily Thornberry has said she is considering entering, while Tooting MP, and former deputy leader candidate, Rosena Allin-Khan has ruled herself out.
Candidates have until Thursday evening to get nominations from at least 80 Labour MPs in order to take part in the contest.
They will also need the backing of either 5% of local parties, or three Labour-affiliated groups, including two unions.
Those who clear the bar face a vote by party members, with the winner announced on 25 October.
