Britain's position paper on border with Ireland worrying: Barnier

BRUSSELS, Sept. 7 (Xinhua) -- Britain's position paper on its future border with Ireland "worries me", EU Chief Brexit Negotiator Michel Barnier said on Thursday.

Solution on the Irish border had to be "unique" and would require flexibility from both sides, Barnier said during a press conference for the release of EU's new document on the Irish border issue.
