Masked men hijacked and torched a bus in Northern Ireland early Monday in an attack linked to British unionists’ opposition to the post-Brexit trade protocol.

Opposition to the arrangements that have created trade barriers between Northern Ireland and the rest of the UK was a factor behind rioting that flared in several loyalist areas across the region in April.

Brussels was “preparing for the worst” over Brexit on Wednesday after the UK signalled the EU’s offer to scrap up to 80 per cent of checks on goods entering Northern Ireland was not enough to resolve the bitter dispute over the Irish border.

The Democratic Unionist Party's boycott of North-South Ministerial (NSMC) meetings in protest at the Northern Ireland Protocol is an unlawful breach of the pledge of office, a High Court judge has ruled.

"..the goalposts continuously seem to change from the perspective of David Frost’s negotiation strategy and I think now that we’re seeing the goalposts shift once more."

Brussels says renegotiation UK is suggesting will mean more instability for the region.

DUP leader Sir Jeffrey Donaldson said his party will seek to block checks at Northern Ireland's ports under the Brexit deal - and if his demands aren't met, the unionists will walk away from Stormont.

Economic advantages of NI’s new trading arrangement overlooked by rejectionist rhetoric.

DUP MP Sir Jeffrey Donaldson has urged the UK Government to intervene to resolve the issues that have hindered the flow of food products.
