Labor Will Challenge UK PM on Brexit Deal, Corbyn Says by Reuters LIVERPOOL, ENGLAND -- British opposition Labor leader Jeremy Corbyn said Saturday that his party would challenge Prime Minister Theresa May on any Brexit deal she could strike with Brussels, and he said there should be a national election if the deal fell short. Britain said Saturday that it would not "capitulate" to European Union demands in Brexit talks and again urged the bloc to engage with its proposals after May said Brexit talks with the EU had hit an impasse. "We will challenge this government on whatever deal it brings back on our six tests, on jobs, on living standards, on environmental protections," Corbyn told a rally in Liverpool, northern England, on the eve of Labor's annual conference. "And if this government can't deliver, then I simply say to Theresa May the best way to settle this is by having a general election." Labor's six tests consist of whether a pact would provide for fair migration, a collaborative relationship with the EU, national security and cross-border crime safeguards, even treatment for all U.K. regions, protection of workers' rights, and maintenance of single-market benefits.
