Brexit clause 'irrevocable', British law chief says

Notification of article 50, the EU clause that governs an exit from the bloc, is "irrevocable", British attorney general Jeremy Wright told the London High Court on Monday. The British government's top lawyer was speaking at a hearing in a case brought by claimants who say that it should be the parliament, not the government, that triggers article 50. Wright said they were trying "to invalidate the decision already taken".
