Is Boris Johnson the Prime Minister of the UK in name only? He seems to have forgotten about the rest of the UK in his speech as it was mainly about what people can and can't do in England.
Are there police on the border crossings in Wales and Scotland?
This crisis must be playing into the hands of people who would like to see the other countries in the UK as sovereign states recognised by the UN (as Richard Osmond would say)
Personally speaking, I think it would be good to have England as its own country. And good for the other countries as well. We could of course co-operate economically, have freedom of movement and free trade etc.
