David Frost, Britain’s trade deal negotiator, has warned the Cabinet that Brussels talks are heading for collapse. He told ministers to ‘take the moral high ground’ when speaking to their counterparts across the Channel in the face of Brussels stubbornness. He urged them to step up their ‘no deal’ planning in case talks over a new trading arrangement break down. Downing Street is preparing to issue warnings that the UK is heading for an ‘Australia-style deal’ - which in reality means tariffs on imported and exported goods under World Trade Organisation terms. Boris Johnson is expected to tell the EU27 to set new rules for their negotiator Michel Barnier, otherwise any hopes of a deal fade. If progress is not made at the next online UK-EU negotiators meeting there is talk in Whitehall of a British walkout. A senior Government source said, ‘Breakdown is entirely possible.’
