Martin Gore was a professor at the Institute of Cancer Research and also worked at the Royal Marsden Hospital.

The Duke of Cambridge once described him as an inspiration, and the Royal Marsden's chief executive said he had "inspired generations" of doctors.

The cause of his death is not known. The Times reported he died suddenly following a yellow fever vaccination.

Prof Gore was an oncologist for more than 35 years, researching ovarian cancer, melanoma and renal cell carcinoma.

He worked at the Royal Marsden Hospital for over 30 years and was made its medical director in 2006.

The cancer expert was made a CBE in the Queen's birthday honours in 2016 for services to oncology.

Prof Gore was also awarded the The Royal Marsden's Lifetime Achievement Award in 2015.

At the time, the Duke of Cambridge, who is the president of the Royal Marsden, described Prof Gore as "one of the pioneers of 20th Century cancer care, and a friend, colleague and a trusted doctor to many" and hailed his "compassion and kindness".
