Inside both the main parties lurk many people who recognise a good deal of the above, but it is more than their political life is worth to say so.

Before the last election, David Cameron said that the three letters N-H-S were as important to him as “education, education, education” had been to Tony Blair.

Then Mr Cameron moved Mr Gove for being too controversial. Mr Hunt has been anaesthetised.
