Labour's top contenders to become the next Prime Minister are nearly all at risk of losing their seats if there were to be a general election today, a new poll has shown.
But GB News has been told by a polling expert that only one remaining frontbencher will be able to hold onto their seat.
Just over a week ago, Sir Keir was dealt a staggering blow at the ballot box, leading to Labour losing its 27-year-long grip on the Senedd and swathes of support across England and Scotland.
Angela Rayner, Wes Streeting, Ed Miliband, Al Carns and Yvette Cooper have all been marked as potential successors to Sir Keir Starmer following Labour's disastrous set of local elections.
But, in just three years' time, the Prime Minister could be forced to bid farewell to the majority of his frontbench - and almost all his rivals at that, national polling has shown.
Ms Cooper, who sits in Pontefract, Castleford and Knottingley, is forecast to win 37.9 per cent, coming second to Reform UK's 49 per cent.
Meanwhile, Al Carns, whose name was thrown into consideration last week, is due to win 23.5 per cent of the vote in Birmingham Selly Oak. Reform UK could take 26.9 per cent.
Over in Manchester, Ashton-under-Lyne's Angela Rayner could be booted out by Reform UK as well.
Ed Miliband is forecast to hold onto his seat at the next election

The former Deputy Prime Minister is set to take home 22.7 per cent, while Nigel Farage's party could win 32.9 per cent.
Mr Streeting is due to take on an independent candidate, who he narrowly beat back in 2024 by a mere 0.2 per cent of the vote.
The next time Britons head to the ballot box, the former Health Secretary's share could drop to 19.3 per cent, while the Independent could scramble to victory with 24.4 per cent.
Nevertheless, Ed Miliband, who has held onto Doncaster North for more than 20 years, is forecast to continue his firm grasp on the Yorkshire seat.

The pollsters at Electoral Calculus have shown the former Labour leader is predicted to win at the next General Election with 38.6 per cent of the vote.
Meanwhile, Reform UK is set to come second on 29.9 per cent of the share.
Electoral Calculus made its prediction based on opinion polls between April 8 and April 24, 2026, sampling 15,213 people.
But Mr Miliband's success will have been diminished from his 2024 victory when the MP won a comfortable majority with 52.4 per cent of the votes cast.
"Only Ed Miliband is likely to hold Doncaster North, partly because Reform didn't stand there in 2024, so are starting from a lower base," founder and CEO of Electoral Calculus Martin Baxter told the People's Channel.
Last week, Mr Miliband was widely suspected of preparing a leadership bid if the opportunity arose.
Allies of the Energy Secretary told PoliticsHome "he has the numbers" to trigger a contest for No10 if Greater Manchester Mayor Andy Burnham was not able to do so.
The revelation came as Mr Streeting stepped down from his role as Health Secretary and admitted he had "lost confidence" in Sir Keir.
In his resignation letter, the Ilford North MP stopped short of mounting a leadership challenge as doubts hurtled through Westminster over whether he had sufficient support from party colleagues to trigger a contest.
In the Labour Party, MPs require the backing of 80 other MPs to trigger a leadership contest.
