The Campaign to Stop Killer Robots is a group of non-governmental organizations who seek to pre-emptively ban lethal autonomous weapons. First launched in April 2013, member organizations joining the Campaign to Stop Killer Robots have urged governments and the United Nations to issue policy to outlaw the development of "lethal autonomous weapons systems" (LAWS). The United Kingdom opposed such campaigns, with the Foreign Office declaring that "international humanitarian law already provides sufficient regulation for this area".
