TNS BMRB show 8 point Tory lead

TNS BMRB have released a new poll, topline figures with changes from a week ago are CON 39%(+3), LAB 31%(-1), LDEM 19%(-2). Fieldwork finished on Wednesday so is more up to date than poll earlier in the week.

Since then I have some more details about the methods TNS BMRB are using - it is a face to face poll (making them the only political pollster still doing them now MORI have switched to phone polls), though the voting intention question itself is self-completed. They weight by normal demographics, plus past vote. My understanding is they use they use the actual 2005 vote shares without adjustment for false recall, like Angus Reid do. Finally they weight by likelihood to vote.
