“Why are you still here?”

As they exit international bodies, the US and UK are refusing to give up their seats at the tables they plan to leave. The question is whether their international partners will let them get away with it.

This week, the difficult negotiations over the UK’s exit from the European Union began in earnest in Brussels. David Davis, the UK’s chief negotiator, squared off against Michel Barnier, his EU counterpart.

Davis called for both sides to “get down to business” for arranging a swift British exit from the EU. He then promptly went back to London, 60 minutes later. He gave no explanation for his own swift departure, which left the EU negotiators perplexed. Just days earlier, Barnier had warned the UK that it is is running out of time to negotiate its exit, which must be completed by March 2019. “The clock is ticking” he said sternly.
