Urmstongran you are again one hundred percent correct in your post @08:20 today. This whole saga has no been all about saving Cummings from the "wolf pack", it has been as much about Johnson appearing as a strong and unmovable leader in the light of Britain finally withdrawing from all its connections with Europe at the end of this year.
The United Kinkdom will approach the above with as many as five or six million unemployed due to the Covid crisis. The message that Johnson wished to portray to the European Union trade negotiators, and many in his own party, is that no matter how Europe may perceive Britain as being in a weak position in those negotiations due to the foregoing, its government is not one for moving.
If Starmer could not concieve that situation until yesterday, then his powers of political judgment has to be very much open to question.
