Labour's lead in the opinion polls has been cut to a single point in a sign Ed Miliband's party has lost ground since the Budget.

The Opinium survey for the Observer places Labour on 33%, a slide of two points from a fortnight ago, and the Tories on 32%, after a gain of two points.

The poll puts Ukip down a point on 15% while the Liberal Democrats are unchanged on 10%.

The online survey was of 1,936 British adults between March 25 and 28, around a week after the Budget was announced by George Osborne.
