EU referendum: Remain target Johnson in TV debate
Boris Johnson has said Britain could "prosper as never before" outside the European Union but was accused in an ITV debate of vying to be the next PM.
Nicola Sturgeon said he was "only interested in David Cameron's job" and Conservative Amber Rudd also attacked his reported leadership ambitions.
He said it was easier to concentrate on "personal stuff" and said the Leave side were offering "hope" over fear.
