Over the last few years there have been many examples of government PPSs breaking ranks and criticising the very government they are members of them. Only rarely is any action taken against them.
The latest is Eric Joyce, the PPS to Bob Ainsworth. He has called the MoD court case seeking to claw back compensation payments as "wholly wrong". He's right and some would say courageous to speak out in such a way. Others might say it would have been more courageous to resign on such a matter of principle.
But it says a lot that the Labour whips are letting it be known that his job is not in danger. What it says is that they can't be bothered to paper over the cracks in their crumbling edifice.
