The British Supreme Court has ruled that Prime Minister, Boris Johnson's decision to suspend Parliament was unlawful.

He suspended Parliament for five weeks earlier this month, saying it was to allow a Queen's Speech to outline his new policies. But the apex court today said it was wrong to stop Parliament carrying out its duties in the run-up to the Brexit deadline on 31 October.

Prime Minister's office in Downing Street said it was currently processing the verdict.

Delivering its conclusions, the Supreme Court's President, Lady Hale, said, the effect on the fundamentals in British democracy was extreme.

The President said the decision to advise Queen to prorogue Parliament was unlawful because it had the effect of frustrating or preventing the ability of Parliament to carry out its constitutional functions without reasonable justification.

Lady Hale said the unanimous decision of the 11 Justices was that the decision of suspension of  Parliament was unlawful and it was for the Speakers of the Commons and Lords to decide what to do next.

House of Commons Speaker John Bercow welcomed the ruling and said the House of Commons will reconvene tomorrow.
