Boris Johnson has promised the British people that he could and would "get Brexit done" - even saying that if he (and the Conservatives) wins the upcoming election, he might be able to "get Brexit done" in just days or weeks. Is this possible? What would it mean? Is it getting Brexit done if the UK is left without trading partners? He has stressed that trade deals are essential, can happen quickly, and that he would prioritise a deal with the United States, so it seems reasonable to assume that getting Brexit done would include getting trade deals done - and least those without which the UK would face shortages in basic goods. If this is so, is it possible to get Brexit done so quickly?
