All through the Brexit debate, and after, people warned that it would cause problems in Northern Ireland. And now here we are:

Loyalist paramilitary groups have told the British and Irish governments they are withdrawing support for the Good Friday agreement in protest at Northern Ireland’s Irish Sea trade border with the rest of the UK.

Brexiters dismissed those concerns as fearmongering.

I don’t know what the end result of this will be, but I can’t imagine it being good.
