Yes, Llywydd, I agree with what the leader of the opposition has said. I too am opposed to the mandation of vaccine passports. We make vaccine certificates available to Welsh citizens because they are sometimes required by people wishing to go for foreign travel or sometimes to attend events elsewhere, but those are matters of choice—nobody is forced to go on holiday, nobody has to attend a concert—and the mandation of vaccine certification I think is quite a different matter. I've had a number of conversations with Ministers in the UK Government and they've always assured me that they have no plans to mandate vaccine certification either. And although the Prime Minister, I now see, is encouraging the use of vaccine certification in certain voluntary settings, I think that's still a long way from mandation.
