The UK’s highest court has ruled that Boris Johnson’s prorogation of parliament was unlawful. Lawyers for Gina Miller, who is bringing a challenge over Mr Johnson’s advice to the Queen to suspend Parliament for five weeks, told the UK’s highest court that the Prime Minister’s decision was an “unlawful abuse of power”. Sir James Eadie QC, representing the Prime Minister, told the 11-strong panel that the suggestion the prorogation was intended to “stymie” Parliament ahead of Brexit is “untenable”.
