The Birth Control Campaign was the pressure group of the Birth Control Trust (a registered charity), although it was set up before the Trust in 1971. It took political action in the form of lobbying for National Health Services in this field, and defended and promoted existing legislation, such as the 1967 Abortion Act. The Trust, however, published pamphlets on aspects of birth control, abortion and population and acted as an information resource centre: being a charity it could defend existing law but not campaign for changes.
From 1971 to 1974 the Birth Control Campaign campaigned for the wider provision of male sterilisation (vasectomy) and for completely free provision of contraception under the NHS. After 1974, when legislation was passed on these matters, the BCC turned its attention to campaigning for improved NHS facilities for contraception, abortion and sterilisation and for these services to be advertised and promoted. The Campaign was also been actively involved in opposing attempts to restrict the terms of the 1967 Abortion Act.
