I see a possible row with Van-Tam, now that he said in today's press conference:

“In my opinion the rules are clear and have always been clear. In my opinion they are for the benefit of all and they apply to all.”

If the government are stupid, they will say: we agree - the rules are clear and Cummings was within them. That will then lead to Van-Tam being asked for more clarification next time he is on (if ever!) and the story keeps going.

I thought the story could have died, but it is now live enough for Keir to raise it at the next PMQ without looking like he is flogging the famous dead horse.
