Fred, no one denies Cameron is a party 'leader', the point is - given that his party did not gain an overall majority - he was not, in effect, 'chosen' by the electorate as Prime Minister. (And, in case anyone imagines I need a lesson on just what elections mean in the UK…I don’t!)
Em, as I'm sure you must have suspected, the only reason your answer is given as 'Best Answer' was because I carelessly clicked on the Mark as Best Answer thing instead of the link directly below it. As regards the link, I had said “in the past half century or so”, and thus I did not feel that going back for longer than a wholecentury was particularly relevant!
Jake, your complaint about the coalition is perfectly valid, of course. It’s just a rolling omnishambles which might well have another two years to run!
