It has been a week since Scottish Labour leader Anas Sarwar piled pressure on Sir Keir Starmer by calling for him to step down.
It’s was the latest bad news story for the Prime Minister a mere 18 months after a spectacular election landslide triumph.
The intervening period has seen a succession of bad news stories for the Premier, along with cabinet scandals and embarrassing u-turns - including on an income tax rise at the last budget.
And the worst was yet to come - courtesy of the scandal linking former British Ambassador to the United States Lord Mandelson to financier sex offender Jeffrey Epstein.
Following Sarwar’s intervention, the Prime Minister appears to have shored up support, with his cabinet offering unanimous support.
But with the crucial Gorton and Denton byelection on Thursday, February 26, followed by the Scottish Holyrood Election and English local elections in May, a series of poor performances at the polls by Labour could see that support vanish.
There is now growing speculation over who will succeed him when he eventually stands aside - or is forcibly removed from office.
Here are the 12 most likely candidates - according to the bookies.
