“So a lot of what we are trying to do this year is to get them to realise that we mean what we say and they should take our position seriously,” he was quoted as saying.

Talks are due to resume in London on Tuesday but they have stalled over Britain’s insistence that it have full autonomy over state aid and its demands over fishing.

Britain says the EU is dragging its feet in talks and has failed to fully accept that it is now an independent country.

“We are not going to be a client state. We are not going to compromise on the fundamentals of having control over our own laws,” Frost told the Mail. “We are not going to accept level playing field provisions that lock us in to the way the EU do things.”

“That’s what being an independent country is about, that’s what the British people voted for and that’s what will happen at the end of the year, come what may,” Frost said.

At heart, Britain is pressing one of the EU’s most sensitive buttons – the fear that a post-Brexit Britain could become a much more agile, deregulated free-market competitor on its border by using selective state aid.

“More and more people have come to the conclusion that Brexit ideology trumps Brexit pragmatism in the UK government,” said one EU diplomat.

“If the UK really wanted to jump off the Brexit cliff edge for ideological reasons, there would be no way for the EU to stop this,” the diplomat said. “If, on the other hand, the UK’s approach became more pragmatic and realistic, there would probably be a good chance to save the negotiations and agree on a deal.”

Frost said a lot of preparation had been done for a possible exit without a trade deal.

“I don’t think that we are scared of this at all,” Frost said. “If we can reach an agreement that regulates trade like Canada’s, great. If we can’t, it will be an Australian-like trading agreement and we are fully ready for that.”
