As the Labour Party embarks on its leadership contest following Sir Keir Starmer's resignation as Prime Minister last month, one name has emerged as the overwhelming favourite to succeed him: Andy Burnham. With his recent return to Parliament in the Makerfield by-election, Mr. Burnham is now poised to take the reins of the party and potentially become the next Prime Minister, given his current status as the only declared candidate.
The nomination period for prospective leadership candidates runs from 9 to 15 July, requiring any MP wishing to stand to secure the support of at least 81 Labour MPs – representing 20% of the parliamentary party. Additionally, candidates must gather nominations from either three affiliated socialist societies and trade unions or 5% of constituency Labour parties, including at least two major unions like GMB, Unite, or Unison, which account for a significant proportion of Labour's affiliated membership.
The schedule for the nomination process is set to unfold as follows: on 13 July, a parliamentary hustings will take place, offering candidates an opportunity to address and answer questions from their fellow Labour MPs. Should Mr. Burnham remain the sole candidate, he would effectively participate in a solo hustings. The affiliate nomination stage opens on 15 July and closes the following day, followed by the constituency Labour Party nomination stage, which is set to commence on 20 July and conclude on 31 July.
Wes Streeting's decision not to challenge Mr. Burnham has reinforced expectations that he will be the only candidate. If Mr. Burnham secures the necessary nominations – in this case, 323 – it would effectively bar any rival from reaching the required threshold of 81 Labour MP nominations. In such a scenario, Mr. Burnham could be declared Labour leader by 17 July, with the official handover to Prime Minister occurring on 20 July, following Sir Keir Starmer's formal resignation to King Charles III at Buckingham Palace.
However, if another candidate emerges, the Labour leadership contest would extend through Parliament's summer recess, commencing after 16 July. In this situation, Sir Keir Starmer would continue as Prime Minister until Parliament reconvenes on 1 September. A ballot among party members and affiliated trade union supporters would then be held between 6 and 27 August, with the result announced on 29 August.
Mr. Burnham has already ruled out an early general election, committing to the 2024 manifesto and indicating that the next election will not take place before its legally mandated deadline of August 2029 – a decision likely influenced by the precedent set in recent years, when seven prime ministers have taken office mid-term without facing a general election victory. The UK has witnessed four such transitions since 2010: Theresa May, Boris Johnson, Liz Truss, and Rishi Sunak.
