Two of Sunday’s polls have already been released – a new poll by ComRes for the Sunday Mirror has topline figures of CON 31%(-4), LAB 27%(-2), LDEM 29%(+8). This was conducted yesterday and today, and is very much in line with the YouGov figures yesterday, showing a surge in support for the Liberal Democrats following the leaders’ debate, pushing them ahead of Labour into second place.

There is also new ICM poll in the Sunday Telegraph which has topline figures of CON 34%(-3), LAB 29%(-2), LDEM 27%(+7). The fieldwork dates are very interesting here – Wednesday and Thursday. The Sunday Telegraph article says the “majority” of the fieldwork was done before the debate, I can only assume it was a large majority, unless ICM do their fieldwork quite late at night! Anyway, most of the shift in ICM’s poll can’t be attributed to the effect of the debate, but rather the publicity around the Lib Dem manifesto launch (remember YouGov’s poll immediately before the debate also showed a 4 point jump for the Lib Dems on the back of their manifesto).

In both cases (as well as YouGov yesterday) both of the main parties have declined as the Lib Dems have surged, but in all cases the Conservatives have lost more support than Labour.
