Jeremy Corbyn now has the support of more than half of those with a vote in the Labour leadership contest, a new opinion poll suggests.

Stark warnings from a string of senior party figures that choosing the veteran left-winger would be catastrophic for its chances of returning to power appeared to have had little effect.

The YouGov survey for The Times of 1,411 eligible voters in the contest to succeed Ed Miliband at the head of the opposition found Mr Corbyn had nearly doubled his lead in a week to 32%.
