In the seemingly endless froth and whirl over MPs expenses generated by expense account journalists employed by tax-avoiding proprietors, indignantly reported by licence fee supported BBC journalists on six figure salaries, one thing has been overlooked: didn't the now deposed Speaker have a point?

Not a single MP has so far seen fit to resign for cheating the public purse yet Michael Martin has gone, forced out by the humbug and hypocrisy of brave Nick Clegg,  David Cameron and others.

Rant over, back to the point. Let's remove the issue of MPs cheating on expenses and look at one of Speaker Martin's main objections  The speaker did question how private data was leaked to the press, allegedly by someone within the House of Commons in exchange for cash.  To date, no-one has yet been able to answer that question.  And we will never know as, in keeping withe the febrile mood,  the Met has said it has no plans to investigate the leak.  Why not? Is leaking personal data now OK?

Just because there is moral indignation as to what MPs have been getting up to does not mean that the method of exposure was legal or correct.

We are already in a period wherby an elected government is deliberately destabilised by systematic leaks designed to damage ministers.  This might seem fair to those who view the governemnt as unfit to be in power and opposition MPS will argue a "public interest" defence.  However, I'm not sure it's not a dangerous path and one that can damage democracy if not checked. Every government will have its enemies - should they be allowed to undermine it through targeted leaks?

When the dust setttles on all this we may have a debate on the use of private data and confidential government documents as political tools - but don't hold your breath.
