Theater, Brinkmanship Mark Brexit Talks Jamie Dettmer Negotiators on both sides of the English Channel say this week is the "moment of reckoning" for a post-Brexit trade deal between the European Union and Britain. But after six months of toxic wrangling the odds are mounting an agreement will not be struck, both British and European officials concede. That result that could poison relations between Britain and its near neighbors for years to come with far-reaching consequences, not only economic but impacted security and intelligence cooperation, too, say analysts. In the run-up to an eighth round of formal discussions that were to start Tuesday in London both sides were locked in an accelerating cycle of furious recriminations, accusing each other of negotiating in bad faith in talks about Britain's future relationship with the bloc of 27 European countries. British Prime Minister Boris Johnson's chief Brexit negotiator, David Frost, said there needs to be "more realism" from Brussels about Britain's "status as an independent country." Patience wears thin Aides of the EU's top negotiator, Michael Barnier, warned patience is wearing thin and that European officials are ready to abandon the meetings this week in the light of plans by Johnson to unveil new legislation that would override key parts of the Brexit Withdrawal Agreement, a framework treaty struck last year that set the terms of Britain's departure from the EU. .
