The Supreme Court is today hearing the second day of arguments in the Brexit legal challenge.

11 of the most senior judges in the UK are hearing the government's appeal to a High Court ruling that Theresa May must let MPs vote on whether to trigger Article 50.

Yesterday, the court heard from government lawyer James Eadie QC and Attorney General Jeremy Wright. The lawyers argued the Prime Minister has authority to trigger the mechanism and begin EU withdrawal processes.

However, the judges questioned why more details haven't been provided about what will be in the Great Repeal Bill, the legislation through which the government intends to legislate for life outside the EU.

The judges also said serious threats have been made to claimants in the case and warned they must be stopped.

The case is expected to last four days in total, ending on Thursday.
