British Prime Minister Theresa May has said her government will trigger the formal divorce process from the European Union by the end of March 2017.
May confirmed the deadline for triggering Article 50 of the Lisbon Treaty in an interview with the BBC on October 2.
The treaty sets the rules for a two-year negotiating process for a country leaving the 28-member bloc.
May said she will give further details during her speech later in the day to her governing center-right Conservative Party's annual conference.
In an interview with the Sunday Times, the prime minister also promised a "Great Repeal Bill" that will overturn the 1972 act that took Britain into what later became the EU.
The repeal of the European Communities Act won't take effect until Britain leaves the EU under Article 50.
