A crisis Cabinet meeting failed to back Theresa May's plan for a ‘customs partnership’ with Brussels. Key Brexit sub-committee members tried to thrash out a model for the UK's future trade links with Brussels in two hours of tense discussions that ended in deadlock. Insiders said that Sajid Javid had been instrumental in rejecting her plan. Mrs May ordered ministers and officials to carry out ‘further work’ on two options and return with revised proposals at a later date. Whitehall sources reported that six ministers oppose her option and want a looser customs arrangement with Brussels. Boris Johnson urged Mrs May to stick to the principles of her keynote speech at the Mansion House earlier this year which clearly stated that Britain would not form any customs union with the EU after Brexit. International trade secretary Liam Fox said the customs partnership was ‘not compatible’ with Brexit.
