UK Prime Minister Theresa May has officially triggered “Article 50” to begin the UK’s departure from the European Union.
Britain’s departure from the EU is “an historic moment from which there can be no turning back”, Theresa May has said.
She was speaking after Britain’s EU ambassador formally triggered the two year exit process by handing a letter to EU Council President Donald Tusk.
A sombre-looking Mr Tusk said it was not a “happy day” for him or the EU.
The European Parliament warned security cooperation was not on the table as it fired its opening salvo in what are expected to be tough negotiations.
