Answer 1

Northern Ireland is the only part of the UK which has a land border with an EU country (Ireland), farmers often have parts of their farm on both sides of the border, so having a trade barrier between Northern Ireland and Ireland is almost impossible, so instead the EU imposed a border between Northern Ireland and he rest of the UK which has upset the unionist politicians in Northern Ireland a lot.
