The Conservatives are continuing to struggle in opinion polls after their drubbing in last month's local elections.
Two polls out over the bank holiday weekend put the Tories on 29%, trailing a long way behind Ed Miliband's resurgent Labour party.
Angus Reid saw Labour increase their vote share to 45%, up four points. Survation saw the Tories slipping one point to 29%, with Labour unchanged on 37%.
For much of the coalition's first two years in power Labour has lagged behind in terms of economic credibility, but Survation's respondents trusted Ed Balls more on 28% to George Osborne's 26%.
Angus Reid found one-third of Britons now approved of the prime minister's performance. Ed Miliband remains just behind on 32% - an assessment unchanged from October 2011.
The polls both represent further bad news for the Liberal Democrats, who are unchanged on 13% in the Survation poll and down two per cent to just nine per cent in Angus Reid's research.
Survation put Nick Clegg's net job approval at -43%, much lower than Mr Cameron's -29% and Mr Miliband's -43%.
Angus Reid said just 21% of Brits approved of the way Mr Clegg was handling his duties, however.
