The personification of flabbergasted

Boris Johnson, the elected Mayor of London, was given to his usual cheek-shuddering defiance last Sunday, as he was hauled over the coals about why he expected London taxpayers to foot his hotel bills when he attends party conferences. He said it was in his official capacity as mayor, but it was pointed out that government ministers pay their own way at party conferences. Then he backtracked further to say it wasn't prohibited by the rules to which he was told it was.
All of this was diverting him from his favourite subject which was building an airport in the Thames Estuary with all the attendant risk of bird strike and aircraft ditching in the water, to drift past City Hall (the glass bollock), their unsubmerged tipping wings pointing J'Accuse-style at the place that caused them to go into the drink, by building a runway in such an unfortunate position. So he wrapped it up, by saying "I don't think it is proscribed under the rules, but if it is proscribed then I will pay it back." The Daily Telegraph revealed that hacks are leaving university without a proper grip on the language, when the reporter covering the story quoted Johnson as saying 'prescribed'. This makes it sound as if the rules mandate it, rather than ban it. What would Samuel Johnson say?
Boris Johnson also pontificated on global matters in the newspaper which misquotes him, though knowing Boris, he might actaully have said 'prescribed', but his subject was particularly awkward - Barack Obama's presidential predecessor, George W Bush and how the latter was a blunderer. Pot, kettle, black spring to mind. Given the screen portrayals of the Roman Emperor Ahenobarbus, if Boris Johnson with his portliness and posturing replaced his scarecrow thatch with Mediterranean locks, one could easily imagine him as the Nero of London. Boris is no murderer (that we know of) and he is an unknown quanity on the harp, but he is a Class-A buffoon with a dark side in a position of power. What a sterling choice the elctors of London made! Who will follow Boris? Russell Brand? What a hoot that would be!
So far Boris has made no lasting impact because all the deputies he appoints keep dropping like flies through scandal, but in this country he is an embarrassment to London. When he goes abroad, he is an embarrassment to this country. At the totalitarian Olympics in Beijing, he insulted the hosts twice by refusing to conform to sartorial conduct (maybe because his size prevents him from buttoning up his jacket) and then rambling on about table-tennis which was really according to his waffle "wiff-waff" (or possibly he has an occasional lisp and was talking about the poor). On can hardly imagine Michael Bloomberg of New York or countless mayors of major cities behaving like that, but then Bloomberg and the others carry themselves with dignity, they have sophistication, rather than acting like the clown, which maybe fine on a TV show, but not in high politics. Boris comes from the upper-crust, but he has no class.
