Keir Starmer’s decision to step down as UK prime minister and Labour Party leader has immediately shifted attention from his departure to the question now dominating Westminster: who will be Britain’s next prime minister? With Labour preparing to launch a leadership contest in the coming weeks, senior figures across the party are positioning themselves for what could become one of the most important political battles in recent years. While no candidate has formally declared their intention to run, a handful of names have already emerged as the most likely contenders to take over both the party and the country. From experienced cabinet ministers to high-profile regional leaders, the race to succeed Starmer is expected to shape Labour’s future and determine the direction of the UK government at a critical time.
Andy Burnham emerges as early eavourite
Among all the names being discussed, Andy Burnham appears to have the strongest momentum. The former Health Secretary and Mayor of Greater Manchester has long been regarded as one of Labour’s most recognisable figures. His recent return to Westminster following the Makerfield by-election victory has fuelled speculation that he was preparing for a larger role in national politics. Burnham’s supporters argue that he combines government experience with a strong electoral record and a proven ability to connect with voters beyond London’s political establishment. His popularity among Labour members and trade unions could also prove decisive if the contest reaches the party’s grassroots. For many observers, Burnham is currently the candidate to beat.
Angela Rayner could rally Labour’s grassroots
Deputy Prime Minister Angela Rayner is another name expected to feature prominently in any leadership race. Rayner has become one of Labour’s most influential figures over the past decade and is widely respected across different wings of the party. Her rise from a working-class background to one of the most powerful positions in government has made her particularly popular among Labour activists. Supporters believe she could offer continuity while also presenting a fresh leadership style. Her strong profile among party members means she would likely begin any contest with a significant support base already in place. However, some analysts believe she may face challenges in attracting support from Labour’s more centrist MPs.
Wes Streeting Seen as Labour’s Moderniser
Health Secretary Wes Streeting has frequently been mentioned as one of Labour’s future leaders and could emerge as a serious contender if he decides to enter the race. Streeting has built a reputation as one of Labour’s most effective communicators and has often been viewed as a leading voice among the party’s reform-minded wing. His supporters argue that he represents a younger generation of leadership and could help Labour appeal to voters who have become disillusioned with traditional politics. While he lacks the national profile of Burnham or Rayner, Streeting is regarded as one of the strongest performers in Starmer’s government and could attract significant backing from Labour MPs.
Shabana Mahmood’s continues to rise
Justice Secretary Shabana Mahmood is increasingly being viewed as a potential future leader, even if she remains less well known to the wider public. Within Westminster, Mahmood has earned a reputation as a capable minister and skilled political operator. Her supporters believe she could emerge as a compromise candidate capable of bridging divisions between Labour’s different factions. Although she would enter the race as an outsider compared with some rivals, leadership contests often reward candidates who can build support steadily behind the scenes rather than dominate early headlines. Many Labour insiders believe her influence within the party is greater than many voters realise.
Could an outsider spring a surprise?
Every leadership contest produces unexpected candidates, and this race may be no different. One name attracting growing attention is Defence Minister Al Carns, whose military background and relatively fresh political profile have led some MPs to view him as a potential alternative to Labour’s established figures. Others could yet emerge as the contest develops. Senior cabinet ministers, rising parliamentary stars and regional leaders are all likely to assess their chances before nominations formally open. History suggests that leadership races can change rapidly once campaigning begins, making it risky to rule anyone in or out too early.
What’s next?
Labour’s National Executive Committee is expected to outline the timetable for a leadership contest in the coming weeks. Until a successor is chosen, Starmer is expected to remain in Downing Street in a caretaker capacity. The outcome of the race will not only determine who leads Labour but also who governs Britain. The next leader will inherit a government facing economic challenges, pressure on public services and growing political competition from opposition parties. For now, Andy Burnham may be the early favourite, but Westminster’s attention is firmly fixed on a contest that could reshape British politics for years to come.
