The British Medical Association (BMA) is the professional association and registered trade union for doctors in the UK. The association does not regulate or certify doctors, a responsibility which lies with the General Medical Council. The association's headquarters are in BMA House, Tavistock Square, London. Additionally, the Association has national offices in Cardiff, Belfast and Edinburgh, a European office in Brussels and a number of offices in English regions. The BMA has a range of representative and scientific committees - including the General Practitioner´s Committee, the GPC - and is recognised by NHS employers as sole contract negotiators for doctors. The aim for the BMA is ‘to promote the medical and allied sciences, and to maintain the honour and interests of the medical profession'.
