YouGov/Sunday Times - CON 37%, LAB 42%, LD 9%

Tonight's YouGov poll for the Sunday Times has topline figures of CON 37%, LAB 42%, LDEM 9%. All this week YouGov's daily polls have been showing Labour leads of between 3 and 5 points, suggesting that there has been a definite change from the neck-and-neck position we were seeing at the beginning of the year. Reasons for poll movements can never really be more than speculation, but as I wrote last month, my guess is a combination of a fading of the "veto effect" from December, less negative perceptions of Ed Miliband than back in January, and perhaps the increased prominence of the issue of the NHS. I'll update on the YouGov poll tomorrow once the full tables are out.

Yesterday we also had new figures from Angus Reid. Their topline figures with changes from January were CON 32%(-3), LAB 40%(+1), LDEM 10%(-1). An eight point Labour lead is the largest any pollster has shown since before the veto, though it's worth noting that Angus Reid have tended to show some of the larger Labour leads of any polling since the election.

There is also an ICM/Sunday Telegraph poll on gay marriage. I don't yet know if it also had voting intention figures but will update as and when.
