The British Medical Association (BMA) is a registered trade union and professional body for doctors in the United Kingdom. It does not regulate or certify doctors, a responsibility which lies with the General Medical Council. The BMA has a range of representative and scientific committees and is recognised by National Health Service (NHS) employers alongside the Hospital Consultants and Specialists Association as one of two national contract negotiators for doctors. The BMA's stated aim is "to promote the medical and allied sciences, and to maintain the honour and interests of the medical profession".
