Pro-Brexit demonstrators, calling on the British government to invoke article 50 immediately, and urging them not to hold a second referendum, shout slogans and hold placards as they protest outside the Houses of Parliament in London, September 5, 2016.

The government did not spell out the mechanism for delaying the vote scheduled for Tuesday.
The UK can reverse Brexit by unilaterally revoking Article 50, the EU's highest court has ruled.
