The UK's highest court has ruled that Boris Johnson broke the law when he advised the Queen to suspend parliament in a bombshell unanimous judgement. The court ruled that it was "unlawful, void and of no effect". Supreme Court President Lady Hale said the prorogation was "void and of no effect", adding: "Parliament has not been prorogued." Does this mean that the Queen no longer has the right to prorogue parliament unless the courts say so. What a mess! Pete is worried about the constitutional crisis.

Commons Speaker John Bercow said the House must "convene without delay" and that he would be consulting party leaders "as a matter of urgency".
