Prime Minister Boris Johnson’s decision to suspend Parliament was unlawful, the Supreme Court has ruled.

Mr Johnson suspended – or prorogued – Parliament for five weeks earlier this month, but judges said it was wrong to stop MPs carrying out duties in the run-up to Brexit on 31 October.

Supreme Court president Lady Hale said “the effect on the fundamentals of democracy was extreme.”

The PM said he “profoundly disagreed” with the ruling but would “respect” it.

A raft of MPs have now called for the prime minister to resign and some say they will attempt to force him out if he does not go of his accord.

A senior government official said the prime minister spoke to the Queen after the Supreme Court ruling, but would not reveal the details of the conversation.
