Brexit on a knife edge as PM Johnson stakes all on 'Super Saturday' vote

Britain's Prime Minister Boris Johnson gestures during a news conference with European Commission President Jean-Claude Juncker after agreeing on the Brexit deal, at the sidelines of the European Union leaders summit, in Brussels, Belgium October 17, 2019.

Britain’s exit from the European Union hung on a knife-edge on Friday as Prime Minister Boris Johnson scrambled to convince doubters to rally behind his last-minute European Union divorce deal in an extraordinary vote in parliament.

In one of the most striking flourishes of the three-year Brexit drama, Johnson confounded his opponents on Thursday by clinching a new deal with the EU that had promised it would never reopen a treaty it agreed last year.
