Boris Johnson would be voters' choice to replace David Cameron as Conservative leader if he stood down before the next election, according to a poll.
The London Mayor was the preferred candidate of 24% of those questioned by YouGov for the Sunday Times, followed by Foreign Secretary William Hague on 14%, ex-leadership candidate David Davis on 6%, Chancellor George Osborne on 3% and Education Secretary Michael Gove on 2%.
Mr Johnson was an even more popular choice as next leader among Conservative voters, with 33% naming him as the best replacement for Mr Cameron, against 24% for Mr Hague and 7% for Mr Davis. And several major Tory donors told the paper that they regard Mr Johnson as a potential future leader.
The poll reflected the so-called "Boris bounce" which the mayor has enjoyed during the London Olympics, garnering favourable headlines even when left dangling from a zipwire in a stunt which went wrong. The proportion of people saying he would make a better leader than Mr Cameron has risen from 23% in July to 30% now.
It confirmed that the Conservatives are still trailing Labour in public opinion, with Ed Miliband's party backed by 44% - 12 points clear of the Tories under Mr Cameron on 32%. Liberal Democrats were on 10%.
Some 58% said Mr Cameron was doing badly as Prime Minister, against 37% who said he was doing a good job. While 39% said he should stay in the job, 37% - including 14% of Conservative supporters - said that he should stand down and let someone else lead the party.
And just 25% approved of the Government's record so far, compared to 62% who did not. Some 64% said that the Conservatives and Liberal Democrats were working together badly in coalition, while just 30% said they were working well.
However, the survey also raised doubts over whether Mr Johnson could revive the Tories' electoral fortunes, with 19% saying he would make them more likely to vote Conservative but 17% less likely, and 55% of voters saying it would make no difference at all.
With figures released last week showing the party's income was cut by nearly half last year, dropping by almost £20 million to its lowest level since 2003, the views of wealthy donors who have supported the Tories in the past will carry some weight in determining the prospects of potential future leaders.
Financier Peter Hall, who has given more than £450,000 to the Conservatives, told the Sunday Times that Mr Johnson could be the right leader for Britain if the country sinks into a very deep recession. He said: Boris's great strength is his confidence and his optimism and his ability to, in an almost Churchillian way, inspire people to hope for a better future."
