I'm told by one Kent MP today that it is now increasingly likely that the gory - or entirely innocuous - details of all MPs' allowances will be published sooner rather than later.

Their publication, under the Freedom of Information Act ruling, had been due in July but there is now a consensus growing that they might as well all be put in the public domain now rather than wait for another rash of stories in the summer months.

The problem here is the logistics of removing from receipts and invoices and bills details such as passwords, bank details and other information that might raise security concerns.

Meanwhile, one MP - who did not want to be named - has said he supports the growing calls for the Speaker Michael Martin to be removed or dismissed after his prickly and petulant performance in the Commons yesterday.

Hugh Robertson, MP for Faversham and Mid Kent, has echoed the fears that public antipathy and anger is so great towards Parliament and mainstream parties that the June elections will see minority extreme parties do well "and we only have ourselves to blame".

Thanet South Labour MP Dr Steve Ladyman, meanwhile, says he "feels embarrassed to be an MP" - adding he had "no idea" that some MPs were submitting such claims.

It will be interesting to see if David Cameron fulfills his threat to discipline his own MPs who quite clearly have made claims that are hardly in the spirit of the rule. The political advantage would be that any action could be seen as taking a decisive stance on the issue, no doubt prompting calls for the other parties to follow suit.

On the other hand, if he acts now and it later emerges that others have transgressed, he may face calls to take more action.

I am surprised that neither Gordon Brown or Nick Clegg has gone down a similar path yet. I'm also surprised that, with one or two exceptions, more MPs have not yet volunteered to repay money they have claimed for dubious reasons - let alone being ordered to do so.
