independent– Failure to strike an EU trade deal will land a “serious” blow to the UK economy and a “strongly negative effect on trade, productivity and jobs in the longer term”, the OECD has warned, as Michael Gove admitted Brexit talks were “getting down to the wire”. With just 30 days until the transition period ends, business secretary Alok Sharma has written to nearly five million firms to outline “the top actions they need to take”, urging them to prepare for new paperwork and procedures, as the government announced it would build a new Border Operation centre to ease “short-term disruption”. Ireland’s Taoiseach is braced for delays until February, joining Labour in accusing the UK government of placing a “very significant” burden on businesses. Meanwhile, some 70 Tories are expected to rebel against the government over its new coronavirus tier system, after being left unimpressed with Downing Street’s costings of the rules, which claimed it was impossible to make any “meaningful” predictions about their economic impact. Labour and the SNP are expected to abstain during Tuesday’s Commons vote.
