Michael Gove and Boris Johnson make their joint pitch with assistance from Dan Hannan.
Update: Hannan is becoming like an optical isomer of the Cheshire Cat: smile disappearing with everything else remaining. Not least his insisting that he always had insisted that migration would not be noticeably decreased.
Still, at least he never threatened to revoke residency status of EU nationals in the event of a referendum win. Unlike Nicola Sturgeon.
