YouGov April Poll
As well as the Scottish poll today also saw the publication of YouGov's monthly GB poll. The topline figures with changes from their last poll are CON 37%(-2), LAB 32%(+1), LDEM 18%(+1). The changes in this poll alone are insignificant, but the drop in Conservative support does match ICM's poll in the week, as does the Lib Dem increase (though it is obviously at a much lower level).
We'll probably never find out for sure if there is a genuine weakening in Tory support, since unless there are any polls in the Sunday papers this is probably the final voting intention poll before the local elections, after which comes the deluge! Local, Scottish and Welsh elections results will themselves likely have an effect upon the polls as some parties are seen as "winners" as some as "losers". More importantly the elections are widely expected to be quickly followed by Tony Blair's resignation, which will change the whole landscape of British politics.
