Raggy:
Did you mean to say I emailed my PM earlier today or was 'PM' a typo for 'MP'.
I ask because ABCD appears to think that the reply you quoted was from Boris.

The response you quoted was not as clear cut as it appears.
"If press reports are correct, Dominic Cummings has fallen short of the standards we expect of every individual, never mind a person who should be setting an example. If he was unsure what the rules were then he could have got advice from medical experts and those in charge of the programme at the very highest level. At the very least he could have made it publicly clear what he intended to do ahead of travelling north.
I agree with you that his position is untenable and he should be relieved of his post."

The two 'if's give your MP as much wriggle room as members of HIGNFY adding "allegedly" to some sentences.
As for suggesting that he should have made his travel plans public. Apart from Royalty, no-one does that.
