Prime Minister Boris Johnson faces a Brexit showdown with parliament on Saturday after clinching a last-minute divorce deal with the European Union that his Northern Irish allies oppose.
In an extraordinary Saturday sitting, the first since 1982, parliament will vote on approving Johnson's deal. Britain is due to leave the EU on Oct. 31.
But Johnson, whose Conservatives have no majority in the 650-seat House of Commons, will face a deeply divided parliament where his opponents are trying to force both a delay to Brexit and another referendum.
Other options include collapsing his government so that others can take control
