A Wiltshire doctor who filmed himself sexually abusing female patients with his James Bond-style wristwatch will appeal against his 12-year jail sentence today.

Dr Davinder Jeet Bains, 47, used a secret camera hidden inside his watch to assault more than two dozen women at a medical practice in Royal Wootton Bassett, where he was a trusted GP.

Police described Bains as a "sexual predator" and said he had filmed up to 300 women while the sentencing judge branded him a "disgrace to the medical profession".

Bains was also struck off the medical register in August last year when the independent Medical Practitioners Tribunal Service panel found his fitness to practise was impaired because of his convictions.

Some of his victims at the Tinkers Lane Surgery spoke of their shock at discovering what the "pervy doctor" had done to them.

One woman, in her 30s, said she felt "violated and humiliated" at seeing the footage and said she had "lost faith in the NHS".

Malaysian-born Bains filmed the attacks on his Tieex watch, which has been likened to something out of a 007 film.

It had a built-in camera on the face - with simple on and off buttons to record - and can be bought on the internet for less than £60.

Bains, of Nyland Road, Swindon, committed offences against 27 women - aged from 14 to 51 - between July 2009 and June 2012.

He admitted a total of 39 charges at Swindon Crown Court: 13 of assault by penetration, 13 of voyeurism, 11 of sexual assault and two of sexual activity with a child.

He also asked for a further 65 offences to be taken into account and his not guilty pleas to four other charges will lie on file.

The police investigation began in June 2012 when a 17-year-old girl told officers she thought Bains had filmed her as she showered and said she had been sexually assaulted by him.

When detectives arrested Bains at his surgery they discovered his wristwatch, and later recovered 361 high-quality video clips from his laptop.

The court was told that two of victims complained to the managers at Tinkers Lane surgery about his behaviour but no action was taken.

Judge Douglas Field told Bains he had breached the trust people put in their doctor and had committed the offences for his own "sexual gratification".

Bains was also placed on the Sex Offenders Register indefinitely and given a Sexual Offences Prevention Order.

NHS England published a report in November last year into the safeguarding of children and vulnerable adults at Bains's former practice which found a senior colleague had "ongoing concerns" about his behaviour but was unsure what to do about it.

Four areas where the practice could make improvements were identified in the report.

These were complaints, chaperoning patients for intimate examinations, reporting and investigating serious incidents of concerns, and supporting and protecting staff who wished to raise issues.

The surgery confirmed that all identified actions had been undertaken and had provided evidence to demonstrate it, an NHS England spokeswoman said.

Bains's appeal will be heard before the Lord Chief Justice of England and Wales, Mr Justice Sweeney and Mr Justice Nicol at Canterbury Crown Court.
