ComRes/IoS - CON 34%, LAB 40%, LDEM 11%

ComRes's monthly online poll for the Independent on Sunday and Sunday Mirror is out, and has topline figures of CON 34%(-3), LAB 40%(nc), LDEM 11%(+1), Others 15%(+2) (including UKIP on 6%). Changes are from ComRes's last online poll, conducted prior to the budget. The Labour lead is smaller than the bigger leads we saw from YouGov, Populus, Angus Reid and TNS-BMRB this week, but the trend is the same - the Conservatives losing support and falling into the low 30s.

For methodology anoraks, on the straight voting intention question UKIP and the Lib Dems were actually level on around about 9% each. The difference in ComRes's final figures comes firstly from the squeeze question that ComRes asks people who say don't know (respondents to that were much more likely to say Lib Dem than UKIP), and weighting by likelihood to vote (in their online polls ComRes only include supporters of minor parties when they say they are 10/10 certain to vote, but include Con, Lab & Lib Dem voters who say they are 5/10 or more likely to vote).
