PM Johnson said he will get Brexit done by January 31 next year. He will use his control of Parliament to outlaw any extension of the Brexit transition period beyond 2020. Britain will not extend the implementation period and the new Withdrawal Agreement Bill will legally prohibit government agreeing to any extension, a senior government official said on Tuesday. By enshrining in law his campaign promise not to extend the transition period beyond the end of 2020, Johnson cuts the amount of time he has to strike a trade deal to 10-11 months from nearly three years. He is sending a message to the EU, whose leaders have cautioned London that more time would be needed for a comprehensive trade deal.
