An ICM opinion poll for The Sunday Telegraph shows that a key group of Right-of-centre voters are much more attracted to Ukip’s policies on immigration, government spending and same-sex marriage than to the Tories’ stance on the issues.
This same group — made up of those who have yet to decide which of the two parties to support — also rates Ukip’s Nigel Farage as a better party leader than the Prime Minister. The group make up one in 10 of all voters and their support is crucial to Mr Cameron’s chances of electoral success.
