Yes, unless ‘exit day’ in the EU Withdrawal Act 2018 is amended by statutory instrument. The procedure for this is set out here https://www.hansardsociety.org.uk/blog/changing-eu-exit-day-by-statutory-instrument. This states “Normally, from laying to making the SI, the draft affirmative procedure takes around six weeks.
However, given the steps outlined above, the process could be accelerated. We see no insuperable procedural obstacle to proceedings on the ‘exit day’ SI being completed by 29 March if the draft SI were laid, for example, on Friday 22 or Monday 25 March.”
No draft SI has yet been laid.
