It's not just Ireland. There are towns crossing the English-Welsh border and English-Scottish border which has been an issue with the increasing fragmentation of the UK in the last year. Particularly in lockdowns people officially can't go to their local shops as it's "over the border". Pretty ridiculous but it reinforces the idea that UK is looking more and more like separate areas -- an idea that the present government appears to want to support?

I don't think it's just the lack of respect for the Good Friday Agreement (I wonder if Raab has read it yet) the unity of the UK as a whole is looking quite strained to me.

[Just my private opinion.]
