Patients are not being told about the disgraced physicians, surgeons and GPs, who are still working in surgeries and hospitals across the country
Up to 927 doctors could still be practicing despite being convicted for crimes such as possession of indecent child images, trafficking drugs, kerb crawling and causing death by dangerous driving.
Medical chiefs claim they cannot ban all sex offenders from working because it might breach their human rights.
But patients are not being told about the disgraced physicians, surgeons and GPs, who are still working in surgeries and hospitals across the country.
Those doctors, who have not been struck off the medical register and who have been found guilty of possessing child sex images are even thought to still be treating children.
The figures, obtained by the Daily Mirror through a Freedom of Information request, show that a total of 927 doctors have kept their jobs despite having a criminal record.
Some of them have committed more than one offence.
None of the patients treated have been informed.
Campaign groups yesterday asked the General Medical Council, who released the figures, to tell patients if their doctors have a criminal past.
Roger Goss of Patient Concern told the Mirror: 'Patients should be made aware if their doctor is found guilty of serious criminal offences that could affect their care and be allowed to make up their own minds if they want to risk being treated by them.'
'The problem is that the GMC is funded by doctors while their prime duty is to protect patients but these two things often come into conflict.'
