For the last week Cameron and Boris Johnson have been competing in how bloodthirsty they’re going to be with returning jihadis – keep them out, burn their passports, cancel their citizenship…And now, this guy comes along saying they should be allowed back home.

Richard Barrett, a former counter-terrorism chief at MI5 and MI6, that’s who. So we don’t need to listen to what he’s got to say, do we?
