Liberty, formerly, and still formally, called the National Council for Civil Liberties (NCCL), is an advocacy group and membership organisation based in the United Kingdom, which challenges unjust laws, protects civil liberties and promotes human rights. It does this through the courts, in Parliament and in the wider community. Liberty also aims to engender a "rights culture" within British society. The NCCL was founded in 1934 by Ronald Kidd and Sylvia Crowther-Smith (later Scaffardi), motivated by their humanist convictions.
