I’m hardly a fan, but by process of elimination Ken gets (has got) my vote. Sorry, Boris; I just don’t believe you’d be up to the task.
Fingers crossed for status quo. I am, as ever, the political conservative (note capitalisation). And, like Ken, a card-carrying Londoner. Besides, Ken’s a Tulse Hill lad.
