Britain's Prime Minister, Theresa May, will officially communicate her country's decision to exit the European Union on March 29.
The UK government said May would notify the 27 other members of the Union about Britain's decision to leave, and that negotiations around the exit were then likely to begin at the earliest.
The development comes nine months after 51.9 per cent of British citizens voted for breaking away, compared with 48.1 per cent who wanted to remain a part of a unified Europe.
There are restrictions under Article 50 on discussions on the terms of the exit and future relations, in the absence of a formal communication by Britain to the other members of the Union, about its decision to leave.
With this development, Brexit should finally take place in March 2019, given the two-year time frame given to Britain to break away.
A formal statement to the House of Commons is expected to be made after Article 50 is invoked.
