The Article 50 notification itself will come in the form of a physical letter to the European Council with “some kind of handover” expected, a U.K. official familiar with the planning said. However, it is yet to be decided, even at this late stage, who will deliver it. Sending the notification via email has not yet been ruled out.
Britain’s Ambassador to the EU Tim Barrow would be the obvious messenger. However, U.K. government sources insist that no decision has yet been made about who will hand it over or who will receive it.
A senior government source familiar with the thinking of David Davis, the secretary of state for exiting the European Union, expected that the letter would be in May’s name, positive in tone (crucial to getting off to a good start, No. 10 believes), and would reiterate the U.K.’s position that both the terms of exit and the new relationship should be settled, in parallel, within two years.
There is unlikely to be any new information about the U.K.’s goals, as Downing Street considers the recent Brexit white paper to be its final word on the subject until negotiations actually begin.
