The U.K. must make concessions on the Brexit bill and give assurances on the Irish border by early next month if talks are to advance to trade this year, European Union President Donald Tusk said. “I made clear to Theresa May that this progress needs to happen at the beginning of December at the latest,” Tusk said after a meeting of EU leaders in Gothenburg, Sweden. “While good progress on citizens’ rights, we need to see much more progress on Ireland and on the financial settlement.” The EU says negotiations on the U.K.’s divorce bill, the protection of rights of European and British citizens and the Irish border must make “sufficient progress” before leaders can allow talks to advance to trade and the potential transition arrangement. May wants that to happen at a summit next month. Tusk spoke with May on the sidelines of the meeting in Gothenburg. He said he would meet her again next Friday.
