He will screw up and resign in fairly short order (hopefully) never to be heard of again.
Talking of which, does anyone know if as Foreign Secretary he HAS to give up his newspaper column, or if that is discretionary (accepting of course that he has no discretion)?
I remember when George Brown had to give up because of all his "tired and emotional" episodes, which made Charlie Kennedy's look insignificant.
My father once met him walking across the Downs above Jevington (where he lived towards the end of his life) and he pompously pronounced on being greeted: "I PREFER not to be recognised". I once saw him parked at the East end of the old Polegate station up platform, waiting to board the solitary first-class compartment in the front carriage up to town to collect his House of Lords allowance.
