On 4th May, the Independent reported that British weapons sales to Saudi Arabia could be ruled unlawful after legal action by campaigners was given the go-ahead. Judges have granted the Campaign Against the Arms Trade (CAAT) permission to appeal a ruling by the High Court in July 2017 that allowed the UK to continue granting export licences despite allegations British weapons had been used to kill civilians in Yemen. Lawyers representing CAAT argued that the decision to grant the licences was against British arms export policy, which states that the government must deny applications “if there is a clear risk that the items might be used in the commission of a serious violation of international humanitarian law”.
