David Cameron's approval ratings have fallen sharply and Labour now lead the Tories by two per cent, a new poll has shown.
The Ipsos MORI survey for Monday's Financial Times showed the Conservative leader's net approval rating has fallen from plus 14 points in January to minus two points this month.
Labour also has a narrow lead, by 37 to 35 per cent over the Conservatives, on voting intention among those "absolutely certain to vote".
The survey, taken after the Tory conference, does not show the 'bounce' which pollsters sometimes expect after a high-profile annual conference.
The fall in approval for Cameron is not accounted for by core supporters turning away from him, but from those voters who were initially undecided but now say they are dissatisfied with his performance.
This dissatisfaction is particularly marked among women, the poll shows.
Meanwhile a YouGov poll in the Telegraph showed voters have mixed views over Conservative tax policy.
At present, only one voter in four views the Tories as the best party to handle taxation.
But asked which party was best on taxes, nearly half of YouGov's respondents replied either that "no party was any good" or that they "had no idea".
And a new Populus poll for the Opinion Leader Forum think tank found that the likely next Labour leader, Gordon Brown, leads Cameron by 27 points among swing voters.
Asked who they would prefer to be the next prime minister, putting aside party preferences, 51 per cent chose the chancellor and 24 per cent Cameron.
Populus interviewed more than 1,000 people, but only 242 were swing voters - meaning those results are subject to a higher margin of error.
