There is no "hypocrisy" in Jeremy Corbyn's calling his Shadow Cabinet to heel. When he was rebellious, he was a backbencher.
If they wish to be rebellious, then they are free to become backbenchers. They could, and perhaps should, be replaced.
Especially in view of the sheer scale of his victory, many of us have been horrified at the quite unnecessary extent of his magnanimity, which his enemies have not reciprocated in the slightest.
