He could surprise everybody and do a half decent job.
Lets face it he's not technically in the job yet and already there are rumblings, so why can't the Tories do what any sane party SHOULD do, put him on a trial basis for say six months till we leave the E.U. then judge him.
O.K. it's the Tories, o.k. it's Boris, not a great start, but even I would not judge his new role till he's at least been given a chance.
