MPs’ expenses claims, forms and receipts are now published by the Parliament, minus the pertinent information (redacted), for example, to see whether an MP had flipped his or her second home. More embarrassment will probably follow this publication. Throughout this sorry saga, one thing that struck me about the claims was their pettiness, such as claims for jellied eel or tea lights, as well as their brazenness.
There is a mass of information which will need some digging: I think Guardian’s attempt to use readers to sift the forms and receipts is a clever idea. People are fed up and wouldn’t mind giving a few minutes to review documents. See Guardian: Investigate your MP’s expenses
