France has taken the hardest line of the member states in recent weeks, including its insistence that an outline of the future relationship should be detailed. Other states suggested it should be allowed to be vague in order to ease the passage to a deal, after the EU rejected key planks of it on customs and the single market. Emmanuel Macron has urged his EU counterparts to stand firm against Theresa May in Brexit negotiations after the PM urged the bloc to give ground in talks. The French president said that EU unity must take precedence over any other considerations. Other leaders took a softer line. Xavier Bettel of Luxembourg said ‘compromise from both sides, not from one side’ was necessary and Irish PM Leo Varadkar told reporters that Mrs May was ‘working hard’ on the issue of Northern Ireland, and that she appeared to be ‘very sincere’.
