Two in three voters think the country needs a new Government at the next election, a new survey shows.
The Ipsos Political Monitor - run between January 18-25 - found a clear majority wants to punish the Tories at the ballot box.
The survey said a massive 66% think it's time for a change, regardless of whether they think the Tories have done a good job or not.
Some 70% believe the Conservatives have done a poor job while just 20% described the Government as competent - compared to 62% who labelled it incompetent.
As Rishi Sunak approaches 100 days in No10, the poll for Ispos also showed Labour enjoying a 25-point lead over the Conservatives.
It comes after a torrid fortnight for the Prime Minister who was issued with a fixed penalty notice and was forced into sacking Tory Chairman Nadhim Zahawi.
Meanwhile, Keir Starmer leads Rishi Sunak on who the public think would make the most capable Prime Minister by a margin of 39% to 33%.
In November, Mr Sunak led the Labour leader by 41% to 35%.
But 44% of those surveyed said they do not know what Mr Starmer stands for compared to 40% for the Prime Minister.
Gideon Skinner, the head of political research at Ipsos, said: "Both Rishi Sunak and his party still face significant challenges at the polls.
"The public remain sceptical about how effectively the Government can deliver on their main concerns on public services, the economy and cost of living, and now the Prime Minister's own ratings are also slipping".
He added: "Combined with much less apprehension about the prospect of a Labour government than in 2019, this is all helping to create a sense among Britons that it is time for a change.
"However, there are also areas for Labour to be wary of - Keir Starmer still has more to do to define what he stands for, and while 2019 Conservative voters are hardly happy with the way the Government is running the country, this group still needs more convincing that things would be better under Labour".
Ipsos interviewed a representative sample of 1,001 adults aged 18+ across Great Britain. Interviews were conducted by telephone between 18-25 January 2023.
