Boris Johnson has published long-awaited plans to rip up parts of the Brexit deal he signed in 2020.
Ministers insisted their changes to the Northern Ireland Protocol do not breach international law, and Boris Johnson claimed they were "not a big deal" and "trivial".
But the EU's Maros Sefcovic blasted: "Unilateral action is damaging to mutual trust and a formula for uncertainty". Irish premier Micheal Martin added: "It's very regrettable for a country like the UK to renege on an international treaty."
