London: British seekingsure PM Theresa May this week to renegotiate her Brexit deal should heed EU warnings that it will not succeed, Ireland’s foreign minister warned on Sunday. imon Coveney said attempts by Brexit supporters to remove or set a time-limit on a controversial “backstop” clause on the Irish border would never be accepted by Brussels. “Listen to what people are saying in Europe,” he told BBC television, saying May’s Brexit deal was “a balanced package that isn’t going to change”. The European Parliament will not ratify a withdrawal agreement that doesn’t have a backstop in it, it’s as simple as that,” he added.
