Britain’s top diplomat warned Monday that the country could crash out of the European Union next year without an agreement on future relations with Brussels because of the hard line taken by EU negotiators.

“This is because I think that many people in the EU are thinking they just have to wait long enough and Britain will blink. And that’s not going to happen.”

Foreign Secretary Jeremy Hunt told reporters in Berlin after meeting German counterpart Heiko Maas that “there is now a very real risk of a Brexit no deal by accident.”

“This is because I think that many people in the EU are thinking they just have to wait long enough and Britain will blink,” he said. “And that’s not going to happen.”

Big differences remain between Brussels and London over the terms of a new trade setup and the issue of how to regulate the U.K.’s only land border with the EU, between the U.K.’s Northern Ireland and the Irish Republic.

A substantial number of lawmakers in British Prime Minister Theresa May’s Conservative Party party favor a complete break with the EU — a so-called “hard” Brexit — rather than the “soft” option proposed by May, which calls for a “common rule book” with European nations that would govern trade in goods.

Hunt, on his first bilateral visit since coming to office, said “Germany is not just one of Britain’s best friends in Europe but one of our best friends in the world.”

He insisted that the trip to Berlin “is not about a charm offensive.” Still, London appears to want to win over the leaders of Europe’s biggest economy to put pressure on EU negotiators to avoid a messy split.

“Without a real change of approach from the EU negotiators we do now face a real risk of no deal by accident. And that will be incredibly challenging economically,” said Hunt.

“Britain will find that challenging but in the end we will find a way not just to survive but to thrive economically,” he said. “But my real concern is that it will change British public attitudes to Europe for a generation.”

Maas said his country “doesn’t want a disorderly Brexit. We want a deal.” But he acknowledged that on the Irish border issue, at least, “further talks will be necessary to reach practical solutions.”

Maas declined to comment on the threat from Britain’s lead negotiator on Brexit that London might not pay its 39 billion pound ($51 billion) divorce bill if no trade agreement with the EU is reached.

The EU parliament as well as national parliaments of EU nations and Britain need to ratify a deal before the U.K. leaves in March.

New UK Brexit chief: We May Not Pay Exit Fee if No Deal

Britain’s slow move away from the European Union took a new twist Sunday as the new Brexit chief suggested that Britain might not pay its 39 billion pound ($51 billion) divorce bill if no trade agreement with the European Union is reached.

Brexit Secretary Dominic Raab told the Sunday Telegraph that there must be “conditionality” between Britain making the hefty exit payment and its ability to create a new relationship with the EU.

“You can’t have one side fulfilling its side of the bargain and the other side not, or going slow, or failing to commit on its side,” he said, implying that the threat of withholding payment might get Brexit talks back on track.

Britain and the EU remain far apart on terms of a new trade setup. May’s Conservative Party is also deeply split over what Brexit policy to support. Raab replaced David Davis, who resigned two weeks ago to protest May’s “soft” Brexit plan.
