British opposition Labour Party leader Jeremy Corbyn moved a step closer to paving the way for another referendum on European Union membership by trying to use Parliament to grab control of Brexit from Prime Minister Theresa May.

With the clock ticking down to March 29, the date set in law for Brexit, the United Kingdom is in the deepest political crisis in half a century as it grapples with how, or even whether, to exit the European project it joined in 1973.

Since May's divorce deal with the EU was rejected by 432-202 lawmakers last week, the biggest defeat in modern British history, lawmakers have been trying to plot a course out of the crisis, yet no option has the majority support of Parliament.
