I'm so glad you said this. I've said a couple of times that I don't trust there was no UK govt hand in this somewhere. I held back because I don't want to look like a conspiracy theorist. This A-Z spat delivers a Brexit & vaccine victory to Tories & UK press portray EU as inept.
This is not a positive PR win for UK - but then I'm not Tory. I want UK fully vaccinated but not at the expense of others. If UK govt are not involved in A-Z's decision to renege on agreement they should have discussions with them & EU to help satisfy fair distribution.
