Andy Burnham remains the overwhelming favourite to become the next Prime Minister.
The race to be the next Prime Minister has been thrown wide open following a dramatic weekend in Westminster, with mounting speculation that Sir Keir Starmer could be preparing to announce a timetable for his departure from Downing Street.
Pressure on the Prime Minister intensified after Andy Burnham's commanding victory in the Makerfield by-election, where the former Greater Manchester mayor secured more than 55% of the vote and strengthened his position as the overwhelming favourite to succeed Starmer.
Reports suggest a growing number of Labour MPs and cabinet ministers believe a change in leadership is now inevitable, while Burnham's supporters claim he has secured enough backing within the Parliamentary Labour Party to mount a successful challenge.
With uncertainty surrounding Starmer's future and several senior Labour figures weighing up leadership bids, betting markets have reacted swiftly. Here's a look at the latest odds on who could become the UK's next Prime Minister.

Next Prime Minister Odds
Who is Favourite to be the Next Prime Minister?
Andy Burnham – 1/20
Andy Burnham has become the clear frontrunner in the betting after his emphatic return to Westminster in the Makerfield by-election.
His odds have been cut from as long as 1/5 into 1/20 (best price William Hill) with some bookies offering 1/100.
The result has been viewed by many Labour MPs as proof that Burnham can reconnect the party with voters in areas increasingly targeted by Reform UK. His victory margin exceeded expectations and has fuelled speculation that he now has enough parliamentary support to force a leadership contest or even secure an uncontested path to the top job.
Several reports over the weekend suggested senior Labour figures believe Burnham has momentum firmly behind him, while prominent voices within the party have openly questioned whether Starmer can continue as leader.
With political markets reacting to the possibility of an imminent leadership transition, Burnham's odds of 1/20 imply bookmakers see him as the overwhelmingly likely successor should Starmer step aside.
Alistair Carns – 30/1
Defence Minister Alistair Carns remains a distant second favourite in the market at 30/1.
While Carns has not been publicly linked to an active leadership campaign, his profile has grown significantly since entering government and some bettors appear to view him as a potential compromise candidate should the contest become more open than currently expected.
At present, however, there is little indication that Carns has the parliamentary support required to challenge the leading contenders, with attention instead focused on Burnham and the future direction of the Labour Party.
Ed Miliband – 33/1
Former Labour leader Ed Miliband is the third favourite at 33/1 despite not being widely viewed as a likely candidate.
Miliband remains one of the party's most recognisable figures and currently serves in the cabinet, but recent reporting has suggested he is among senior ministers urging Starmer to clarify his future rather than positioning himself for a leadership bid.
While his experience ensures he remains on bookmakers' radars, current market sentiment suggests bettors believe the race is increasingly centring around Burnham rather than a return to a previous generation of Labour leadership.

Andy Burnham Prime Minister Odds
Andy Burnham's odds of 1/20 reflect the dramatic shift in Labour's leadership picture following the Makerfield by-election.
The former Greater Manchester mayor has long been regarded as one of Labour's most effective communicators outside Westminster, and his decision to return to Parliament was widely interpreted as the first step towards a leadership challenge.
Since securing victory in Makerfield, reports have emerged claiming Burnham has the backing of a substantial number of Labour MPs, with supporters arguing he is best placed to halt Reform UK's rise and rebuild Labour's standing with working-class voters.
Speculation has also grown that senior rivals could decide against mounting a challenge if Burnham's support continues to expand, potentially paving the way for a smoother transition should Starmer announce plans to step down.
While political situations can change rapidly, bookmakers currently view Burnham as the overwhelming favourite to become the next Prime Minister, with his odds suggesting he is significantly ahead of every other potential contender in the market.
