THERESA May’s Tories have opened up a significant 16-point lead over Jeremy Corbyn’s Labour, according to the latest ICM Unlimited UK wide poll.

It puts the Conservatives on 43 per cent, up four, and Labour on 27 points, down two.

Such a lead in the ICM series of snapshots has not been seen since October 2009.

It has been calculated that if the poll were reflected at the next General Election, then the Tories would see an increase in seats of 45 to 376 while Labour would see a fall of 44 to just 188. Mrs May’s nominal majority of 12 would jump up to around 100.

The increased lead suggests a May bounce less than two weeks after she took over as Prime Minister from David Cameron and despite the concerns about the Brexit process. But it could also reflect growing public disaffection with the bitter recriminations continuing to plague Labour as it goes through yet another leadership contest.

The latest ICM poll also places Ukip on 13 per cent, down, the Liberal Democrats on eight, down one, the SNP unchanged on four and the Greens unchanged also on four.
