"The most important thing I think now is for us to look to the horizon", said Britain's Foreign Secretary, Boris Johnson, ahead of a meeting with other foreign ministers in Luxembourg "Think about the future, and think about the new partnership, the deep and special partnership that we want to build with our friends".
Davis, however, told the press he was entering the negotiations with a "positive and constructive" frame of mind, and he will present a joint press conference this evening from Brussels with the EU's chief negotiator Michel Barnier.
Barnier said there will be one week of negotiations every month and the two sides will use the time in between to work out proposals. "We must lift the uncertainty caused by Brexit", said Barnier.
