From their website:
BBC News gathers and produces national daily news, business, political and current affairs programmes on BBC television and radio.
It is also responsible for the continuous news channels BBC News 24, BBC Parliament, BBC World, interactive services, Ceefax and the BBC News website.
BBC News is highly respected both in the UK and around the world, from the World Service which reaches a global audience of more than 150 million listeners with hundreds of bulletins in more than 40 languages every day, to the BBC's flagship television news programme The Ten O'Clock news programme on BBC One.
The breadth and depth of BBC news coverage is unrivalled, with subject specialists who can throw a spotlight on people and stories which are not widely known.
The bulk of programming comes from the news centre in Television Centre, west London - the largest such operation in the world.
Political programming, including the BBC Parliament channel, is based in the heart of Westminster at Millbank while international radio programming comes from the home of World Service - Bush House in central London.
Around 3,500 people work for BBC News, both across the UK and in key news bureaux around the world.
