When she appointed him I thought perhaps her plan is to give him enough rope. I think he wants to be PM and she's hoping he'll make too many gaffes as FS. Although he could be going down the Farage/Tr*mp route of thinking he's speaking on behalf of the man in the pub, appealing to people who want plain, blunt speech. As Anya says, arms deals are the priority, obviously. Maybe Jalima's hit the nail on the head.
Horrifying and appalling all round.
