EU leaders to hold special Brexit summit in late April: sources

BRUSSELS (Reuters) - The European Union's 27 leaders will meet at the end of April to agree their negotiating lines for Brexit talks, after London sends in a formal notification that it wants to leave the EU on March 29th, three sources in Brussels said on Tuesday. The meeting is a necessary step before the negotiations between Britain and the 27 remaining EU states can start formally. (Reporting by Jan Strupczewski and Gabriela Baczynska)
