Brexit Talks Enter Key Phase With Clock, Trust Running Out

The U.K. and European Union are starting a key week of Brexit talks, with the bloc stiffening its demands over how any trade deal will be enforced after losing trust in Boris Johnson because of the prime minister’s attempt to rewrite last year’s divorce agreement.

The final round of scheduled discussions between the EU’s chief Brexit negotiator, Michel Barnier, and his British counterpart, David Frost, begins in Brussels on Tuesday with officials on both sides expressing cautious optimism a deal can be reached.
