Tory defector Mark Reckless is on course to win back his Commons seat for Ukip in the upcoming by-election in Rochester and Strood, according to a new opinion poll.
The new survey by Survation for the Mail on Sunday has Ukip nine points ahead of the Conservatives in the constituency.
The pollsters found that 40% of those who voted Tory in 2010 were planning to switch their vote to Ukip.
There is another by-election in Clacton before the Rochester vote, with fellow Tory defector Douglas Carswell a clear favourite to win and become Ukip's first elected MP.
