Under-fire Liz Truss is already less popular than shamed Boris Johnson was when he left office - with just 17% of the public backing her, latest figures show.
The Prime Minister faces an uphill struggle after bombshell polls showed Labour has taken a massive lead over the floundering Tories.
In a week which saw markets descend into chaos and the Bank of England forced to plough billions into saving pensions funds, an enormous 55% of the British public said they disapprove of the job she's doing.
Even as Mr Johnson clung onto the top job in late June - days before a mass Tory exodus finally brought about his downfall - he could boast 27% public support.
The Opinium polling found that 48% of people asked think Ms Truss should resign after less than a month in the top job, with just 26% wanting her to remain in place.
The divided Tories go into their first conference since a summer of blue-on-blue bickering, with many high profile figures - including former leadership contender Rishi Sunak - opting to stay away.
Even at his worst moments in January, after the Partygate scandal broke, Mr Johnson had 22% approval - although the number who disapproved of him rocketed to 65%.
It piles pressure on a Prime Minister already struggling to hold her party together, with a YouGov poll last week showing Keir Starmer's Labour has an enormous 33 point lead.
The picture looks even more bleak for Kwasi Kwarteng, who has come under fire after it emerged he met business leaders at a champagne reception just hours after delivering his devastating mini-budget.
Opinium said just 15% approve of the job he's doing, while 55% disapprove and a whopping 51% think he should quit.
Three quarters believe the government has lost control of the economy - a view held by as many as 71% of 2019 Conservative voters.
Just 18% of the wider public, and 24% of Tory supporters, believe the party has a grip on the economy after this week's carnage.
The polling data will be much better received at Labour Party HQ, with Keir Starmer seeing a big jump in his approval rating - with 38% in favour and 29% against him.
The opposition has also seen a dramatic rise in intended vote share - with 46% saying they intend to vote red and 27% backing the Tories.
Just one in five believe the Truss government is best placed to handle the economy, compared to 39% who think Labour would do better.
James Crouch, Head of Policy & Public Affairs at Opinium said: “This is the worst poll result we have shown for a Conservative prime minister since the 2010 general election.
" Liz Truss has managed to reach the depths of the poor personal ratings of both Theresa May and Boris Johnson at the end of their tenure, within weeks of taking office and within days of her government’s first major action.
"While the prime minister’s own approval ratings have plummeted, she has also contributed to the Conservative government as a whole losing its political credibility and reputation for economic competence almost overnight.
"If Liz Truss can turn it around, all of us are waiting with bated breath to see how she can.”
