The referendum was three years ago? That’s not enough of a delay?
Correct. It’s far too long - the UK has already asked TWICE for a delay.
Now they should give the people of northern Ireland what they voted for, namely to stay in the customs union with no borders with the Republic. Then they should leave on October 31.
Scotland would soon leave but then both Scotland and NI are drags on the English economy, so better if they are cut off.
