The EU is demanding the UK ditches plans to change Boris Johnson’s Brexit deal “by the end of the month” or risk jeopardising trade talks. The UK has published a bill to rewrite parts of the withdrawal agreement it signed in January. The EU said this had “seriously damaged trust” and it would not be “shy” of taking legal action against the UK. But cabinet minister Michael Gove said the UK had made it “perfectly clear” it would not withdraw the bill. The government says Parliament is sovereign and can pass laws which breach the UK’s international treaty obligations.EU chief negotiator Michel Barnier said “trust and confidence are and will be key”, after the latest round of UK-EU trade talks wrapped up in London on Thursday. His UK counterpart David Frost said “significant” differences remained over a free trade deal, but added discussions would continue in Brussels next week.
