TNS BMRB have a new poll out today. Topline figures are CON 34% (+5), LAB 36% (-3), LD 9%(nc), UKIP 13%(-1). These are particularly unusual figures, TNS normally show some of the biggest Labour leads of any company, and for the last six months or so have been pretty consistent in showing Labour leads up around ten points. Suddenly we have a big narrowing of the Labour lead, dropping right down to 2 points, the lowest I have from TNS since November 2011. Even withstanding the small lead in YouGov’s poll this morning, I’d treat any poll showing such a big movement with no obvious cause with some caution, I suspect the next TNS poll will show things reverting to rather more usual figures.
