Really? Rumoured to have some personal issues, which are not to be sniffed at, which would surely rule him out of contention, if they were remotely true.
Ak. Ok. Well if that is the case that would explain why he has seemingly disappeared. I recall reading / hearing some comments to that effect, following Johnson's outing with the police on some dawn raids last week, but thought they were purely jokes etc. Perhaps not then.
If that were the case, would it be something I would find hard to believe? Absolutely not.
