Sir Vince Cable has suggested Britain's perceived migration problems are rooted in the "absurd" approach taken by Theresa May when they served in government together.
Cable made the comments during the SunTalks debate, hosted by The Sun and talkRADIO and moderated by Julia Hartley-Brewer. He appeared alongside Foreign Secretary Boris Johnson, shadow foreign secretary Emily Thornberry, and UKIP's Patrick O'Flynn.
Cable served in the coalition government alongside May, who held the crucial position of home secretary during their time as Cabinet colleagues.
The former business secretary blasted this "obsession with this number, this £300,000 number [sic] which Theresa May chose... she was responsible for seven years [but has] never got anywhere near it because it's completely unreachable and absurd economically."
He also said May was completely isolated in the coalition as "we all agreed her figure was economic nonsense."
