This is the historic moment a UK judge ruled Boris Johnson's suspension — or proroguing — of parliament was unlawful.
"The decision to advise Her Majesty 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," Supreme Court President Brenda Hale said, reading out the historic decision.
"Parliament has not been prorogued. This is the unanimous judgment of all 11 justices," she added. "It is for parliament, and in particular the speaker and the (House of) Lords speaker, to decide what to do next."
