Margaret Beckett was embarassed on the BBC’s Daily Politics yesterday after PMQs, by vehemently insisting it was clear the Prime Mentalist had just promised a free vote on the expenses Statutory Instrument. Beckett was all over the place and Brillo had some sport out of her discomfort.

In the morning at the Lobby briefing, Downing Street briefed that the expenses Statutory Instrument was to be a whipped vote, yet during PMQs Brown seemed to announce a free vote, until finally it was confirmed at the afternoon Lobby briefing that it had been withdrawn. Downing Street blames Harriet Harman in her capacity as the Leader of the House of Commons.

Guido suspects that the return to a dithering shambles in government spin owes something to the “deputy PM” Lord Mandelson being in India trying to smooth over the mess left by Miliband – though the Indian PM is refusing to meet him in a deliberate snub.

The mySociety organised online campaign against the MPs expenses cover-up saw 90% of MPs contacted by voters opposed to the move. Thousands were mobilised very quickly. Despite this a back room deal was still all set to go ahead until Dave vetoed it.

Shadow Leader of the House Alan Duncan now claims that the Tories rejected the moves on principle, it is fair to say that on this issue Cameron has “got religion” and thinks the old ways are finished. (The LibDems have always been sound on transparency.) However an old school axis of expense fiddlers exists which is cross party. Tory bed blockers and Labour backbenchers all have a highly developed sense of entitlement to pocketing the taxpayer’s money. This particular alliance with Labour, quietly sorted out by Sir Michael Spicer, chairman of the 1922 Committee, in his capacity as shop steward for Tory MPs had agreed a nod and a wink deal with Labour to get the motion passed. Cameron scuppered the deal when he ordered that all Tory MPs be whipped to vote against it. Brown only U-turned after it became clear that the deal was off.
