BIRMINGHAM, England (Reuters) - Britain’s Brexit minister warned the European Union on Monday against trying to bully the United Kingdom into signing a divorce deal that would undermine the unity of the country.

“If the only offer from the EU threatens the integrity of our Union then we will be left with no choice but to leave with no deal,” Raab told the Conservative Party conference in the English city of Birmingham.

“What is unthinkable is that this government, or any British government, could be bullied by the threat of some kind of economic embargo, into signing a one-sided deal against our country’s interests,” Raab said.

“I find it hard to believe that they would, for narrow political ends, seek to punish Britain in such a crass and counterproductive way,” he said.
