A doctor treating a prostitute asked her: "Do clients give you orgasms?" during consultations, which have led to a tribunal hearing.

Dr Zulfiqar Ali, who allegedly posed the question during a consultation at Glasgow Addiction Services between 2001 and 2013, faces being struck off.

He denies his questions were sexually motivated, stating that he was entitled to ask such personal questions because of his long experience in the field of sexual health.

The General Medical Council (GMC) disagrees, however. The GMC also claims Dr Ali failed to find out about the prostitute's history of drugs and alcohol.

Dr Ali previously admitted culpability relating to complaints brought against him by another woman, whose medical notes he did not check at a meeting in 2011. He then failed to report that she then fled the consultation early and in a distressed state.

The "fitness to practice" hearing continues.
