It has been a bad week, allegedly, for the banksters of Barclays — though as ever a much worse week for its clients and its home nation, Great Britain.

And the American CEO of the bank is under some pressure, but Bob Diamond is hanging on, like a good American-born banking executive, as he casts aside others to take the blame for his leaking ship.

Marcus Agius, the chairman of Barclays, is resigning in a move intended to take some of the pressure off the embattled bank’s chief executive Bob Diamond, who has faced calls to quit in the wake of the interest rate fixing scandal.

But Bob Diamond is still doing well — look who is coming to London next month with his hands-out?

…the former Massachusetts governor will attend a private fund-raising dinner in London next month.

The price of invitations dwarfs the amounts paid for such fund-raisers in British politics. Each guest must pay between $25,000 (£17,000) and $75,0000 (£50,000) for a seat at the dinner, which will be hosted by Bob Diamond, the chief executive of Barclays.

Mitt Romney is nothing if not a man with impeccably odious timing.
