Medical chiefs have confirmed talks are under way with the police about sharing information on gun owners so that patients who could be a danger to themselves or others are flagged up.
Discussions have started between the British Medical Association (BMA), the police and the Home Office on how such a system might operate. One suggestion is electronic tags being placed in medical records of patients who own a firearms or shotgun licence.
The move comes just two weeks after taxi driver Derrick Bird shot dead 12 people and injured 11 others in Cumbria.
A BMA statement said: "Such a system can be appropriate, provided it is used as part of the ordinary care given to a patient. It can, for example, be a useful aide-mémoire, to remind doctors that the patient has, or may have, access to a firearm.
"Such a system should not, however, imply that the GP practice has taken on particular obligations to monitor or oversee the mental health of individuals holding firearms licences."
