LUXEMBOURG (AP) — The Latest on Britain's upcoming departure from the European Union (all times local): 4:30 p.m. European Council President Donald Tusk says new thinking is required to end the Brexit standoff and is likening the Irish border problem to the mythical Gordian Knot that cannot be untied. Tusk said Tuesday that "we need maybe a new method of thinking." He says that avoiding a "hard border" between EU member Ireland and the U.K.'s Northern Ireland "looks like a new version of the Gordian Knot. Unfortunately I can't see a new version of Alexander the Great." Legend has it that the ancient Greek king used his sword to cut through the knot.
