LONDON – British Prime Minister Theresa May will trigger article 50 to leave the European Union on Wednesday 29 March, a spokesman has confirmed.

According to international media, the UK’s permanent representative to the EU, Sir Tim Barrow, informed the bloc on Monday that a letter should be expected on that date.

The letter will kickstart a two-year countdown to Brexit and allow negotiations to start between London and Brussels in the coming weeks.

By the end of next week, after he has received May’s letter, European Council President Donald Tusk should have distributed draft guidelines for the negotiations to the 27 other national governments.

Tusk will also summon those 27 leaders for a summit to endorse the final guidelines, probably in early May

May, who was visiting Swansea on Monday, intended to visit Northern Ireland and Scotland before the formal notification was sent by letter on 29 March, Downing Street said.
