IMF head Strauss-Kahn charged over New York 'sex crime'

I don't propose to say anything about the alleged "sex-crime", but I did notice on the BBC web page that
"His accommodation there was described by the New York Times as a luxury suite costing $3,000 per night (£1,900).".
This man is travelling, by himself, at public expense. How on earth can any any Public Official, or his employer, justify spending that amount on a suite?
As our government, and hence out taxpayers, are significant contributors to the IMF, don't they keep an eye on where the money is going?  Our government should insist that, along with the EU, all these international organisations to which we contribute should publish full accounts which include the expenses of their top officials.

Wishful thinking, no doubt, as I would imagine that most of our parliamentarians are busy trying to get onto the bandwagon themselves!
