As well as the YouGov poll (see the post below), there are also new polls today from Populus and TNS BMRB.
Populus has topline figures, with changes from last month, of CON 33%(-1), LAB 42%(+4), LDEM 11%(nc). For those with a Times subscription there are more details here.
Meantime TNS BMRB has topline figures, again with changes from last month, of CON 32%(-3), LAB 42% (+4), LDEM 10%(-1), Others 16%.
So, three polls tonight, with answers that are actually pretty consistent – the Conservatives at 32-33, Labour at 42-43 and slightly more variation on the Lib Dems on 8-11.
