As Britain struggles through the Brexit maze it has now reached the situation where one of three things can happen.

First possibility: Prime Minister Theresa May again presents her plan to Parliament (probably on March 21 but maybe earlier) — which is the EU withdrawal agreement, a legal treaty agreed after lengthy and painstaking negotiations between the U.K. government and the European Union. She wins a narrow majority and the crisis is over, with the United Kingdom then moving on to a two-year gradual and orderly transition to new arrangements with the EU and world trading partners.

Second possibility: The prime minister presents her plan (a slightly revised agreement) and loses again, just as she did heavily a few weeks ago. In that case the official EU exit date for the U.K., March 29, will immediately be postponed (via a request to the EU Commission), either for a few weeks or maybe for several months.
