YouGov show a 7 point Tory lead
YouGov's final poll of the year for the Telegraph has topline figures, with changes from their last poll, of CON 42%(+1), LAB 35%(nc), LDEM 14%(-1). It was conducted between the 16th and 18th December.
Clearly there is no significant change on the last YouGov poll, though collectively their last few polls have been showing a slight trend back to the Conservatives. That trend is not, however, supported by any of the other polling companies, so I'd be slightly wary about reading too much into that just yet.
