Tory lead still fragile, polls suggest

Conservatives remain just four points ahead of Labour in latest YouGov poll

The Conservatives can still not be sure of winning a majority at the election, according to two new opinion polls which suggest a hung parliament is increasingly likely.

The latest daily YouGov survey for the Sun showed the party's lead over Labour remains at just four per cent. The poll put the Tories up one point to 37 per cent, with Labour also up one to 33 per cent and the Liberal Democrats down two to 18 per cent. If repeated at a general election on a uniform swing, the latest figures would leave Gordon Brown 25 seats short of a majority in a hung parliament.

Meanwhile, a new Ipsos-MORI poll for the Daily Mirror showed the Tories' lead over Labour falling to 5 per cent, the party's lowest rating in a MORI poll since 2007. The poll put the Tories down two to 35 per cent, with Labour also down two to 30 per cent and the Liberal Democrats up two to 21 per cent. If repeated at a general election, the figures would produce a hung parliament with Labour 37 seats short of anoverall majority.
