  2. Good morning

    Welcome to day three of our coverage of the Supreme Court, which is hearing challenges to the PM's prorogation - suspension - of Parliament.

    The 11 senior judges are hearing two different appeals over the prorogation - one from the English High Court and one from the Scottish Court of Session.

    During the opening two days, lawyers for the government and campaigners clashed over whether or not prorogation is a matter for the courts.

    Today, the judges are expected to hear submissions from those who have been given permission to intervene in the appeals, including former prime minister Sir John Major.

    The session gets under way at 10:30 BST.
