Dr Deepak Hora was 'delighted but extremely surprised' to win the award, given annually by the RCGP to recognise a GP trainee whose exams and training 'demonstrated outstanding performance'.
Kent-born Dr Hora won a series of accolades at medical school, a first-class BSc in endocrinology, and graduated with distinction as an MBBS.
She opted for GP training, and became the main surgeon doing caesarean sections in her obstetrics post.
In her registrar year, she worked at a practice in King's Cross, London, becoming involved in a drop-in centre for homeless young people, and co-ordinated a health promotion programme for staff and patients.
Dr Hora told GP: 'The appeal of general practice for me lies in the variety and challenge that it offers. I relish the prospect of starting my day with no idea what each patient will bring. It is a difficult job to master and do well, and taking on the challenge is one of the things that attracts me.
'In no other branch of medicine is one encouraged and given so much opportunity to develop skills in a number of different fields both within and outside clinical practice.'
More medical students would be attracted to primary care if they knew what it offered, she said.
Dr Hora is working as a locum in central London, and on a project with Camden Council to transform services for families with complex needs.
