Although the Conservatives have pulled to within two points of Labour in the most recent Mori poll, this would still suggest Labour's majority in the House of Commons would be nearly 100 seats over all other parties.

The voting intentions of the 53 per cent of the electorate who say they are "certain" they will vote when the election comes is 39 per cent for Labour, 37 per cent for the Tories and just 18 per cent for the Liberal Democrats, a swing of 3.7 percentage points from Labour to Conservatives since the last general election.
