The decision by Boris Johnson to suspend Parliament was unlawful, the Supreme Court has ruled.
Mr Johnson prorogued – or suspended – Parliament for five weeks earlier in September, claiming it was to allow a Queen’s Speech to outline his new policies.
But the UK’s highest court said it was wrong to stop Parliament carrying out its duties.
The court’s president, Lady Hale, said: “The effect on the fundamentals of our democracy was extreme.”
She said the unanimous decision of the 11 justices was that Parliament had not been prorogued – the decision was null and of no effect – and it was for the Speakers of the Commons and Lords to decide what to do next.
