UK threatens EU with rewrite of Brexit deal

LONDON — Britain and the European Union were once again at loggerheads over Brexit on Wednesday, after the U.K. government ramped up threats to scrap parts of its trade treaty with the bloc, saying the rules are blocking the formation of a new government in Northern Ireland.

Foreign Secretary Liz Truss said the government would “not shy away from taking action” if it can’t reach agreement with the bloc.

The EU warned that renegotiating the legally binding agreement “is not an option.”

Arrangements for Northern Ireland

— the only part of the U.K. that shares a border with an EU nation — have been the thorniest subject of contention in the U.K.’S divorce from the 27-nation bloc, which became final at the end of 2020.

A deal keeps the Irish border free of customs posts and other checks, because an open border is a key pillar of the peace process that ended decades of violence in Northern Ireland. Instead, there are checks on some goods entering Northern Ireland from the rest of the U.K.

The arrangement is opposed by many of Northern Ireland’s British unionists, who say the new checks have created a barrier with the rest of the U.K. that undermines their British identity. The Democratic Unionist Party, which came second in last week’s Northern Ireland Assembly election, is refusing to help form a government until the arrangements, known as the Northern Ireland Protocol, are substantially changed or scrapped.

Under Northern Ireland’s power-sharing rules, a government can’t be formed without the support of both the main unionist and nationalist parties. Sinn Fein won the most seats last week, the first time a party that seeks to unite Northern Ireland with the republic has topped the voting.

Britain’s Conservative government has accused the bloc of being needlessly “purist” in its approach to the rules, while the EU says Britain is failing to honor a legally binding deal that Prime Minister Boris Johnson agreed to.
