No change from YouGov
YouGov's monthly poll for the Telegraph shows no change at all since their last poll - support remains at CON 41%(nc), LAB 31%(nc), LDEM 17%(nc).
As a whole the polls really are looking very static; after a period of volatility things seem to have settled down to a Tory lead of between 10 and 12 points (which is, incidentally, almost exactly the lead they would need to get an overall majority on an uniform swing from 2005).
