London, Muharram 01, 1438, October 02, 2016, SPA -- Britain will trigger Article 50 of the Lisbon Treaty - which sets the rules for a two-year negotiating process for a nation leaving the EU - by the end of March, Prime Minister Theresa May says, according to dpa. "As you know, I have been saying that we wouldn't trigger it before the end of this year so that we get some preparation in place," May tells the BBC's Andrew Marr Show. "But yes, I will be saying in my speech today that we will trigger [Article 50] before the end of March next year," she says ahead of a keynote speech at the Conservative Party conference. --SPA 12:38 LOCAL TIME 09:38 GMT www.spa.gov.sa/w
