The British Prime Boris Johnson has said the UK will be "walking out" of the EU in 25 days without a deal if Brussels does not compromise.
His words come after the European Commission called off weekend talks, describing the his latest proposals as not providing a "basis for concluding an agreement".
Writing in UK newspapers the Sun on Sunday and the Sunday Express, Mr Johnson said: "After decades of campaigning, three years of arguments and seemingly endless months of pointless delay, it is now just 25 days until the UK's membership of the European Union comes to an end.
"We will be packing our bags and walking out on October 31. The only question is whether Brussels cheerily waves us off with a mutually agreeable deal, or whether we will be forced to head off on our own.
Mr Johnson said the proposals put to Brussels would get rid of the "anti-democratic backstop", avoid infrastructure or checks at the Irish border, and "respect" the Good Friday agreement.
The proposals would also allow the UK "to take back control of our trade policy and do free trade deals with our friends around the world".
Speaking at the Fine Gael Presidential Dinner in Dublin last night, Taoiseach Leo Varadkar said: "I think a deal is still possible.
"But the current position as of today is the European Union, including Ireland, doesn't feel that the proposals put forward by Prime Minister Johnson yet form the basis for deeper negotiations.
Mr Johnson described Labour Party leader Jeremy Corbyn as a "serial wannabe Brexit-wrecker" and rebel MPs as not wanting to deliver Brexit "full stop", adding: "They say they're against no deal, but actually favour no Brexit".
He was optimistic about the likelihood of getting agreement from MPs.
He said to Europe: "Grasp the opportunity that our new proposal provides. Join us at negotiating table in a spirit of compromise and co-operation. And let's make Brexit work for both sides."
A European Commission spokesperson said the UK will be given "another opportunity to present its proposals in detail" on Monday.
