If Kwasi Kwarteng is forced to quit as chancellor over the currency and pensions turmoil, he will earn an unenviable record in British political history.
At present the shortest serving chancellor of the exchequer has been Iain Macleod, who died just a month after being appointed to the Treasury by Edward Heath in 1970.
Second shortest was Mr Kwarteng's predecessor Nadhim Zahawi, appointed after Rishi Sunak quit in July and in the job for just two months in the dying days of Boris Johnson's premiership.
So far, Mr Kwarteng has been chancellor for just three weeks. And Treasury sources are defiantly telling Sky News he won't resign or do a U-turn on his tax cuts that triggered the crisis.
But while Sir Keir Starmer has stopped short of calling for him to quit, some despairing Tory MPs are claiming privately that his position is fast becoming untenable.
As for Liz Truss, who found time to talk to President Zelenskyy of Ukraine but not the British people as the Bank of England stepped in to save the nation's pensions, she too could become an unfortunate record holder.
The shortest serving prime minister so far has been George Canning, who saw off the Duke of Wellington and Sir Robert Peel to land the top job in 1827 but was PM for just 119 days before he died at the age of 57.
The rest of the unenviable league table has Alex Douglas-Home serving for one year and one day, Sir Anthony Eden one year 279 days, Gordon Brown two years and 318 days, Neville Chamberlain two years and 348 days, Theresa May three years and 11 days, James Callaghan three years and 29 days and Boris Johnson three years and 44 days.
This week, as the economic crisis deepened, bookmakers Ladbrokes slashed their odds on Ms Truss being replaced before the year is out from 40/1 to just 11/1.
Kemi Badenoch leads the way with Ladbrokes in the race to take over as Tory leader, at 7/1, while next in the betting to succeed her, at 8/1, is... Boris Johnson.
