The MPs watchdog.

clipped from news.bbc.co.uk MPs' standards chief quits over expenses The head of the Commons standards body has stepped down pending an inquiry into his own expenses - a few weeks after being appointed. The Daily Telegraph alleged Tory MP David Curry claimed nearly £30,000 for a second home that his wife had barred him from using after he had an affair.

What most reports have omitted is that Mr Curry is on another committee which is to rule on the future of MP's expenses and behaviour.
Small wonder there is no trust in MP's!!!
