That was my immediate translation when I saw this headline yesterday:
Theresa May and David Davis to travel to Brussels for urgent Brexit talks
Obviously the British are trying to create an impression of comity with the EU negotiators, to show that misunderstandings are being swept aside, and the negotiations are now going to run smoothly. An impression that is not fostered by this:
Though Downing Street insisted the dinner had long been in May’s diary, EU sources suggested it may have been more last-minute, but were not able to provide confirmation.
On the other hand, given the warnings about the security of post-Brexit food supplies, maybe they were just hoping to get a solid meal.
