Prince Philip has been the Queen's consort since 1952
Prince Philip has become Britain's longest serving royal consort.
He has overtaken the record of 57 years and 70 days set by Queen Charlotte, wife of King George III.
The Duke of Edinburgh's duties as consort began in February 1952 when his wife Princess Elizabeth succeeded her father George VI as monarch. She was crowned the following year.
The 87-year-old Duke, who is known not to like a fuss, is with the Queen at Windsor Castle this weekend and has no planned official engagements.
Even after so many years of service to the country, Prince Philip shows little sign of slowing down. He undertook more than 350 engagements in 2008, and is patron or president of some 800 organisations.
