Brexit legal challenge live: British citizens will lose rights through EU withdrawal, Supreme Court told

A third day of arguments has been made in the Brexit Supreme Court appeal

Brexit at the supreme court: Day Three

Gina Miller's legal representative has outlining the case against the Government in day three of the four day Supreme Court appeal on Brexit.

Lord Pannick QC represented Ms Miller and told the court Theresa May does not have sufficient authority to trigger Article 50 and instead the case must go to MPs.

Representing fello claimant Deir Dos Santos, a hairdresser born in Brazil, QC Dominic Chambers told the court only parliament has the power to take away British citizens' rights, which EU withdrawal would inevitably do.

The court was also told both Scotland and Northern Ireland must approve triggering Article 50 before the Government does so. A majority of people in Scotland (62 per cent) and Northern Ireland (56 per cent) voted to Remain.

The day before, while the court was sitting, Ms May announced during a visit to the Gulf that she will reveal her Brexit plans before triggering Article 50, in what appears to be a signifcant U-turn on her previous position.

• Man arrested on suspicion of threatening Gina Miller
• Theresa May U-turns and says she will reveal Brexit plans
• Government droped amendment to make EU referendum legally binding, court told
• Men speaking for 99.3 per cent of the time during Supreme Court case

Catch up on everything that happened in court today:

The Prime Minister has previously said she plans to trigger Article 50 by the end of this Spring.

If MPs are entitled to vote on Article 50, it could delay Brexit considerably or ensure it is a 'soft Brexit' rather than a 'hard Brexit' as politicians could insist protectionist clauses are inserted before EU withdrawal.

The Supreme Court case is expected to last four days.

A judgment is anticipated for early in the new year.
