The European Union’s chief Brexit negotiator Michel Barnier told Britain on Monday that the time had come for Britain to make a choice on what sort of relationship it wanted with the bloc after Brexit, Reuters reported.

“The only thing I can say: without a customs union and outside the single market, barriers to trade and goods and services are unavoidable,” Barnier told reporters in Downing Street. “Time has come to make a choice.”

“We need also clarity on the UK proposals for the future partnership,” Barnier said.
