Britain's ambassador to the EU, Tim Barrow, told the office of European Council President Donald Tusk on Monday morning that Britain would trigger Article 50 of the Lisbon Treaty next Wednesday, May's spokesman said.
Get your diaries out because Theresa May has announced the date for triggering Article 50: March 29.
Prime Minister Theresa May is set to formally trigger Article 50, the start of the Brexit process on 29 March which will kick off the two years of exit talks.
His warning was mirrored in comments made by EU Commission President Jean-Claude Juncker, who said the United Kingdom would have to accept the deal offered or leave with no deal, after Ms May confirmed next Wednesday as the moment Article 50 would be invoked.

May also faces political dangers at home, most notably in Scotland, where the first minister, Nicola Sturgeon, is seeking another referendum on Scottish independence.
But in his evidence to the committee, Jones said a House of Lords report, published earlier this month, which concluded that leaving the European Union without a deal would mean no legal obligation to pay any financial contribution at all, had been "extremely helpful".
Labour's Keir Starmer said the opposition would hold the government to account throughout the process, claiming the prime minister had failed to provide certainty about her plans or prepare for the "clear dangers" of not reaching a deal at all.
