The UK’s permanent representative to the European Union, Sir Tim Barrow, notified the EU on Monday morning that a letter should be expected on that date. The move will put the UK on course to leave the EU on the same date in 2019.
May, who was visiting Swansea on Monday, intended to visit Northern Ireland and Scotland before the formal notification was sent by letter, Downing Street said.
Downing Street sources had repeatedly said May would take the action to start the Brexit process “by the end of March.”
Earlier rumours that the move would be made last week were quashed by sources close to the prime minister after Nicola Sturgeon declared her desire for a second Scottish independence referendum, leading to speculation that May did not wish to appear cavalier about the future of the union.
