YouGov/Sun - 33/27/31
Final poll I know of tonight is YouGov's daily poll in the Sun. Their topline figures are CON 33(+1), LAB 27%(+1), LDEM 31%(-2). A slight drop in Lib Dem support, but really no significant change from yesterday's figures, and YouGov have still got the Tories and Lib Dems within 2 points of each other, they are pretty much neck-and-neck.
UPDATE: Nothing in particular to do with YouGov, but an interesting point someone made in the comments. One of the important questions we are considering is how long the Lib Dem boost will last and to what degree it will have faded by the time we reach polling day. Someone has reminded me in the comments that a significant proportion of people have postal votes now, so some people will be starting to vote comparatively soon.
