To be honest, I find it a bit confusing to have incoming travel restrictions in the same thread as local lockdowns but since that's where this is being moved: the Welsh First Minister Mr Drakeford has now said that he is writing to Mr Johnson to give him "one last opportunity" to do the right thing and modify English lockdown rules so that they involve not allowing people from high risk area to visit low risk areas.

He explained that he does not want this to be a border issue [I read this as referring to the interpretation made by many in England of the mention by Ms Sturgeon of the possibility Scotland might do the same a couple of months ago if some English areas ended up being far more affected than Scotland] the letter will restate what powers Wales has and that if Westminster does not do the right thing, they will use those powers and effectively ban people from high infection areas in England from entering Wales. Quote from his interview to the BBC last night:"UK ministers were asking me today for the evidence that tells you that if people come from high areas to low areas, that spreads the virus. We’ve got that evidence, we’ll share that with the Prime Minister.

And I will set out in my letter the powers we have and, if he doesn’t act then, we will use them. But I want to offer him one final opportunity to do the right thing. Because that would be fair to people in Wales and people across our border.

I don’t want it to be a border issue. People in England in high incidence areas should not be going to low incidence areas in England, either."

So in practice, either the lockdown conditions change and Government effectively forbids people in, say, Merseyside, from visiting other regions, or the Welsh Government will take its own measures, and ban people from, say, English tier 2 and tier 3 areas from entering Wales (either as blanket ban or more likely with some exemptions for essential travel)
