A doctor who worked for the Queen has been killed in a traffic collision in London.

Peter Fisher, 67, was riding his bicycle through central London on Wednesday when he was involved in a collision with a truck. Police confirmed a 67-year-old cyclist had died at the scene.

“We are all deeply shocked and saddened to learn that Dr Peter Fisher tragically died in a road traffic accident yesterday,” Gill Gaskin, medical director at University College London Hospitals (UCLH), said on Thursday.

“Peter was director of research at UCLH’s Royal London Hospital for Integrated Medicine, and physician to Her Majesty The Queen.”

He is the eighth cyclist to be killed in London in a traffic collision this year

Buckingham Palace said the Queen had been informed of his death.

Fisher was a world expert in homeopathy and had worked as homeopathic physician to the British monarch for about 15 years, according to a report in the Evening Standard.

“He was much respected as a good doctor who saw homeopathy as complementary to medical care. We are all shocked by his tragic loss,” the queen’s former surgeon-gynaecologist Marcus Setchell told the Standard.
