PARIS -- The foreign ministers of France and Ireland are calling for more clarity from the U.K. over its intentions for the Brexit.

Ireland's Charles Flanagan said "it's now over five months since that decision was taken by the British people and I believe it's important now that ... we know precisely what the British plan is," at a news conference in Paris on Thursday.

His French counterpart, Jean-Marc Ayrault, said if the "in-between" situation were to persist for too long, it would cause "prejudice" to the EU.

British Prime Minister Theresa May has said that she will trigger Article 50 of the EU treaty by the end of March 2017 to start the process of removing her country from the EU.
