Boris Johnson has come unstuck during a live radio appearance where he appeared not to know the name of the Tory candidate in the Clacton by-election.
Former 'Bread' actor Giles Watling has been chosen to take on Tory defector Douglas Carswell in the Essex town, with Mr Carswell strongly predicted to become Ukip's first elected MP.
However, speaking on LBC radio, the London Mayor struggled to identify the Conservative who was taking on Mr Carswell.
"We've got a fantastic guy called ... superb man ... Stirling, Girling, something like that," he said.
Mr Johnson admitted it would be a "a disappointment" if the Conservatives lose the seat, but insisted the party would "fight again" for the seat at next year's general election.
