Dr Julian Lewis: As today is blue Monday, the gloomiest day of the year, will the Prime Minister cheer up at least 17.4 million people, and probably many more, by confirming that beyond a shadow of doubt this country will have left the European Union by 30 March?

[The Prime Minister: My right hon. Friend has regularly asked me that question, and my answer has not changed. First, I believe that it is our duty to deliver leaving the European Union and, as he knows, there is a date in legislation for us to leave – it is 29 March. That is the end of the two-year article 50 process.]
