WE already knew this was one of the most rebellious parliaments for years – but things have gone so far now that we all appear to have become de-sensitised to it.

The kind of disloyalty that would have kept Gordon Brown's fingernails short seems to pass without even putting ministers off their lunch.

This week alone there were three significant kerfuffles which at any other time would have caused waves, but somehow two of the three failed to make any mark.

The first was a letter to Downing Street signed by 100-odd Tory MPs calling on the Government to scrap subsidies for wind turbines, which came speedily on the heels of the resignation of the Liberal Democrat Energy Secretary Chris Huhne last week.

I suppose you might say this was just backbench Tories flexing their muscles as the Lib Dems lost one of their strongest political performers.

But if that didn't feel disloyal enough there was another letter to come, again signed by around 100 Tories, no insignificant number when you only have some 300 MPs in total.

Newark MP Patrick Mercer was among those that signed the second letter, calling on the Government to "repatriate" justice powers from the European Union.

This letter too was timely given that the European Court of Human Rights had just passed a ruling stopping the UK Government from deporting the radical cleric Abu Qatada to Jordan.

While it was Home Secretary Theresa May who took most heat over Qatada in the Commons, the implicit target of the letter was another Notts MP, member for Rushcliffe and Justice Secretary Ken Clarke.

Proper Tory righties have still never forgiven Clarke for his indiscretion over Mia the cat at Conservative Conference last year; in fact they have just never forgiven him generally.

But, unusually, Clarke did not top the table for being most vilified cabinet member this week – it is pretty hard, after all, to top someone demanding that you are "taken out and shot". That was the comment made by an unnamed source in Downing Street who spoke to a columnist about Health Secretary Andrew Lansley's handling of legislation to reform the NHS.

After the story about the Health Secretary's life expectancy broke, I contacted yet another unnamed source close to Lansley to see what they made of the apparent adverse briefing from within Downing St.

The deadpan answer I got back was that somebody of little significance had probably been taken for a "three-bottle lunch" and ended up over-lubricating their tongue.

But even if that was the case, it did not stop the issue of NHS reform surfacing at Prime Minister's Questions, like a dead body that just won't stay at the bottom of the lake.

Furthermore, the issue allowed Ed Miliband to continue what I'm tentatively going to call "a run" of good performances at the despatch box.

With doctors, nurses and patient groups all lining up to oppose the changes being made to the NHS, this could only be an easy hit for Eddie; but where in the past he has floundered in front of open goals, this time he gaily popped the ball in the back of the net.

His platform was provided by a posting on a blog run by the Tory Reform Group (TRG) – middle-of-the-road types who would like to quell the excesses of the Conservative right.

The blog claimed that Lansley should "admit defeat" over the NHS reform, giving Eddie the chance to re-jig the old favourite catchphrase of the left – "you can't trust the Tories on the NHS".

In the middle of PMQs, as Cameron failed to answer questions about his broken promise to carry out no top-down reorganisation of the NHS, the Labour leader said: "The Prime Minister says that this is all about reform, but the Tory Reform Group (TRG) has come out against these proposals.

"It comes to something when even the Tories do not trust the Tories on the NHS."

There was a tangible ripple along Government benches as righties fought the temptation to bop the nearest member of the TRG – a group which is chaired by the old enemy, Rushcliffe's Ken Clarke.

The TRG tried to deny Eddie's claims later, saying that the blog post was written by an independent contributor and did not reflect the views of the wider group, but the damage was done.

Maybe next time they will just write a letter like everyone else.
