The three opinion polls published today show the Lib Dems and ‘others’ mainly gaining, indicating that voters are not immediately moving to the two main parties. The 'smaller' vote is not just holding up, but increasing as the campaign gets underway. The one exception is the Populus poll for the Times which has Lib Dems gaining, but 'others' losing ground.
The final pre-campaign opinion polls seem all over the place this morning with ICM and YouGov polls showing a six point difference in the Tory Lead over Labour. This indicates that this may not be an election easily called on the usual basis of a swing from Labour to Tories.
