Indulge me for a moment, the only independent body who can regulate MPs expenses are the public. Not the general public, but people like the blogosphere and the people who make up the media and local constituents.
No QUANGO or arms length government body or private sector organisation is going to have the confidence of the public, parliament should be beholden to the public. We get to chose who is hired and fired. So the public needs the information in an easily processable form.
Sometime soon the House of Commons are going to publish all the expenses information, but as with most government things its going to be in a format that isn't the best for the peopel who will be using the information.
I don't know what format's best, Excel spreadsheets, CSV files, some kind of xml rss feed? I dunno. What I can suggest is that we look at all the MPs who've published their own expenses online and see what different formats they're using and which ones we like best.
I'm compiling a list of MPs who've self-published so far (with links)
