MORI shows 4 point Tory lead

MORI have released their monthly political monitor (their poll earlier this week was a seperate one, commissioned by the Daily Mirror). The topline figures, with changes from earlier this week, are CON 39%(-2), LAB 35%(-1), LDEM 15%(+4). I don't have confirmed fieldwork dates yet, but it was likely done over the weekend.

Given the extremely short gap since the previous lot of fieldwork and the lack of any great world shattering events that could explain a big jump in Lib Dem support, I expect the changes here are no more than normal random sampling error (that is, the variation in the make up between one sample and the next) - though we are getting into the period when I'm slightly wary of polling results anyway as Christmas shopping starts to skew the people who are at home to take phone calls. The overall picture remains a Tory lead in the mid single figures.
