Polls split between Labour and Tory electoral lead

Two polls from the Sunday Times and the Observer have reached contradictory conclusions - with a YouGov survey putting Miliband three points ahead, whilst an Opinium survey put Cameron four points ahead.

The Observer poll, carried out by Opinium, found that Labour's support had dropped two points to 32%, while the Conservatives remained on 36%.

Support for Ukip was found to have risen 2 points to 13% according to the survey, while the Liberal Democrats also gained by one point to 8%.

The poll of 1,995 adults took place on 16 and 17 April, with the BBC "Challengers' Debate" falling inbetween those dates.

A YouGov poll for the Sunday Times revealed Labour were three points ahead.

Ukip's third position with 13% remained consistent in both of the polls.
