PM urges EU to agree Brexit trade deal by ‘end of summer’

The UK has urged the European Union to reach a post-Brexit free trade agreement “by the end of the summer” as Boris Johnson held talks with Brussels chiefs.

The UK had previously indicated that it could walk away from talks with the EU if the “broad outline” of a deal was not visible by the June meeting. But officials played down the prospect of “drama” at the summit, which was being conducted by video link.

I find that slightly positive, though still think a 'no-deal' most likely. Dropping the bluster of stopping talks and switching all the UK focus to no-deal planning is welcome, as is the implicit recognition of how important a deal is for the UK. The EU stance has barely changed since the outset, so the UK is well aware of what the EU will or will not compromise on. No doubt this will be presented as the UK doing everything possible to get a deal if the no-deal is the final situation, but there are glimmers of opportunities in this.

I insist on saying "no-deal" rather than WTO rules, by the way, because parts of the WTO rules include a dispute resolution mechanism in the evert of disagreements, and at the moment that is not operating. Established deals under WTO rules can bumble along for the most part, but setting up new ones will almost certain require disputes to be resolved.
