Reality check.
In total 45 MPs from across the Parties have had queries raised on their expenses ranging from serious to trivial. This relates to the latest round of problems that have emerged. There are a few 'historical' exclusions and the list may well lengthen over the course of the next week.
To put that into perspective that is 45 out of 646. While all the others are not necessarily whiter than white it does show that we should not tar them all with the same brush.
This link shows an interesting graphic of all the cases so far and an assessment made by Westminster insiders of just how serious they consider each indivual case to be.

Some ratings may change, of course, Cameron (himself in the clear) has at least told his MPs to go meet the media and explain themselves, Gove and a few others have done so already. Pity Brown did not do the same thing but at least lets acknowledge that for once he has apologised (a bit late but lets not be too churlish).
I have just found this link to Gove and Duncan explaining themselves. I have to say I am unconvinced personally by Alan Duncan but I do think Michael Gove has been done a relative injustice (while not being totally innocent as he acknowledges).
