One consequence of the Tories moving ahead of Labour for the first time since March 2012 is that MPs of all parties are beginning to discuss the possibility that the Conservatives could win the most votes in 2015 while Labour wins the most seats. Such an outcome is made possible by the first-past-the-post system. While the Tories pile up wasted votes in high turnout areas, Labour efficiently pockets city constituencies where fewer take part.
On a uniform swing, Lord Ashcroft’s poll (which puts the Tories on 34 per cent and Labour on 32 per cent) would leave Labour with 14 more seats (307 to 293) than the Conservatives. David Cameron requires a lead of around four points before his party moves ahead.
