Sir Keir Starmer finds himself in a precarious position following the resignation of his chief adviser, Morgan McSweeney, and mounting criticism regarding his decision to appoint Peter Mandelson as the UK’s ambassador to the United States. The prime minister’s admission of being aware of Mandelson’s ties to Jeffrey Epstein has only intensified the scrutiny he faces from both sides of the political aisle.
A Leadership in Crisis
Since taking office 16 months ago, Starmer’s approval ratings have plummeted, with recent events prompting some MPs, including those within his own party, to question his leadership capabilities. The fallout from McSweeney’s resignation—a departure he attributed to taking “full responsibility” for the controversial appointment—has left Starmer exposed and vulnerable to challenges. With just one MP needed to secure 20% backing to mount a leadership bid, the spectre of a leadership contest looms large.
Potential Contenders Emerge
Angela Rayner
Angela Rayner, the former deputy prime minister, has re-entered the conversation as a potential successor to Starmer. Despite her resignation over tax issues less than six months ago, she demonstrated her political intent by vocally opposing the government’s handling of Mandelson’s vetting documents. Support from trade unions and her recent declaration, “I’m not dead yet,” suggest she is preparing for a potential leadership race.
Starmer has expressed a desire to see Rayner return to government, indicating a willingness to reconcile after her earlier departure. Her influence could be significant, whether she chooses to run herself or lends support to another candidate.
Andy Burnham
Greater Manchester Mayor Andy Burnham has also been frequently mentioned as a serious challenger. His leadership aspirations have been a topic of discussion since mid-2025, with MPs reportedly encouraging him to consider a bid. His recent attempts to contest a parliamentary seat were thwarted by the Labour Party’s National Executive Committee, sparking accusations that Starmer’s camp is attempting to stifle potential leadership rivals.
The growing tensions within the party indicate that Burnham’s name will continue to feature prominently in conversations about Labour’s future.
Wes Streeting
Health Secretary Wes Streeting has long been viewed as a potential leadership candidate. Despite his charismatic public persona, he faces criticism for being perceived as too right-leaning within the party. Recent reports suggest a faction within the party is pushing for his ousting from the Cabinet, further complicating his position.
Streeting has previously highlighted concerns regarding the government’s direction, pointing to a “toxic culture” in No. 10. His ability to resonate with the public could play a crucial role in any leadership contest he enters.
Shabana Mahmood and Ed Miliband
Home Secretary Shabana Mahmood is another name being floated, having received an endorsement from former Prime Minister Tony Blair last year. However, like Streeting, her alignment with the party’s right may limit her chances, particularly if both were to run.
Conversely, Ed Miliband, who previously led the party to defeat in 2015, is experiencing a renaissance as a champion for green policies. His return to the leadership conversation reflects a desire from the left of the party for a candidate who aligns more closely with their ideals.
Why it Matters
The current turmoil within the Labour Party is emblematic of broader challenges facing the political landscape in the UK. As public confidence in Starmer dwindles, the potential for a leadership change could significantly impact Labour’s strategy and effectiveness in opposition. With the next general election on the horizon, the party must navigate these internal divisions carefully to present a united front, lest it squander the opportunity to regain power. The stakes have never been higher for both Starmer and his potential successors as they grapple with the future direction of Labour.
