Nigel Farage told Good Morning Britain there is "not one ounce of complacency from me" after he was selected to stand in the South Thanet seat for Ukip at next year's general election.
"I'm not pretending for one moment that it's going to be easy, but Ukip is offering something different and distinctive," Farage said.
Asked if he would stand down as leader if the party fails to win a single seat at the election, Farage reiterated his comments from last night.
"If we'd failed in the European elections I would have stood down, if we fail next year the party will pick someone better than me, but do you know what? That ain't going to happen," he said.
