Why has Peter Hain posted on his Facebook that the Cabinet is split?

I don't know for sure if Peter Hain's Facebook page is actually Peter Hain. But if it is, why has he posted a Daily Mail article claiming that his views on the Gary McKinnon extradition have caused a Cabinet split??

I managed to grab this screen shot (above) of the post.

It has been well reported that his hostility to the extradition has caused friction with the Home Secretary, Alan Johnson - but to openly post that this is causing tensions within the cabinet is more than a little odd.
