According to BBC News, Vaughan Gething, who announced the covid management plans for Wales for the next three weeks today told the BBC he was "fairly surprised" by the manner of the PM's announcement, and the fact that it did not appear to be underpinned by public health advice.
If the advice exists, he said, "it hasn't been shared with us."
"There certainly wasn't a meeting and agreement between the chief medical officers across the UK.
"There was no meeting between health ministers before this change was made, all the things that have been very normal during the course of the last two years, didn't take place," he said.
He questioned why no medical advice had been provided to underpin the changes.
"Here in Wales I can look anybody and everybody in the eye and say today's changes have gone through that process."
It certainly looks like Boris is winging it.
