Part of Brexit released lorries from checkpoints between the UK and EU (Northern Ireland to Republic of Ireland). Instead they are checked when arriving in NI from mainland UK. This protocol was agreed because of sensitive political border histories. Boris Johnson wants to change this protocol section to make it easier for some goods to move between Britain and NI. But the European Commission vice-president said there was ‘no legal or political justification whatsoever for unilaterally changing an international agreement; it has left us with no choice but to take legal action.’ Mr Johnson insists the proposals are legal, will secure the UK’s future and are set out in a parliamentary bill. The protocol is upsetting the balance of the Good Friday Agreement’. The Democratic Unionist Party, who won the second-most seats in recent elections, is refusing to set up a new ruling Northern Ireland executive with Sinn Féin, who won the most seats, until changes are made to the protocol.
