CAMPAIGNERS have expressed alarm at the amount of closed evidence heard during the High Court case challenging Britain’s arms sales to Saudi Arabia.

Campaign Against Arms Trade (CAAT), which launched the legal action, said that the hearing at the Royal Courts of Justice in London, which closed on Thursday, had been “shrouded in secrecy,” with campaigners and their lawyers shut out of the courtroom.

Evidence heard behind closed doors included the government’s figures on potential violations of international law committed by the Saudi-led coalition in Yemen.
