For the fourth week running the Conservatives and Labour are within one point of each other in the Ashcroft National Poll. The headline result is a reversal of that of the last two weeks: over the past weekend I found Labour a point ahead on 30%, the Tories second on 29%, and the Liberal Democrats down one on 9%. UKIP, the Greens and the SNP remain unchanged at 16%, 7% and 4% respectively.
This is the third consecutive week in which Labour and the Conservatives have commanded a vote share of less than 60% between them.
