Oops! Conservative candidate promises to be first 'female Labour mayor'

Susan Hall has promised to become the first "female Labour mayor" for London in a slip of the tongue.

The Tory mayoral candidate gave an upbeat speech at Conservative Party Conference about her chances of defeating Sadiq Khan in next year's election.

But she ended with a gaffe at the fringe event, accidentally claiming to have switched sides.

She quickly corrected herself.
