Cabinet Office Briefing Rooms (COBR) refers to the location for a type of crisis response committee set up to coordinate the actions of bodies within the government of the United Kingdom in response to instances of national or regional crisis, or during events abroad with major implications for the UK. The constitution of a COBR meeting depends on the nature of the incident but it is usually chaired by the Prime Minister or another senior minister, with other key ministers as appropriate, and representatives of relevant external organizations such as the Association of Chief Police Officers and the Local Government Association.
