If there is no agreement by March 29, Britain will depart the bloc without any deal. That could mean a brutal economic adjustment, as the terms of trade would change overnight, disrupting the flow of goods to and from the continent. In January, the prime minister’s Brexit withdrawal proposals were defeated by 230 votes in the 650-seat Parliament, one of the greatest defeats in British history. If they decide against that, legislators would then be allowed another vote on whether Britain should request an extension of its negotiations with Brussels. One group is determined to prevent the prospect of a potentially chaotic “no deal” departure.
