Prince Philip Duke of Edinburgh

The Duke of Edinburgh has been a constant source of support for the Queen since they married in 1947, but has often caused Buckingham Palace considerable embarrassment with one or two ill-judged comments during his years in public office.

Prince Philip became the UK's oldest ever consort to a monarch today after turning 94 and to mark the occasion there was a 41-gun salute at midday from The King's Troop Royal Horse Artillery. An hour later the Honourable Artillery Company, the City of London's Reserve Army Regiment, fired a 62-gun salute across the River Thames.

Despite his old age, Prince Philip yesterday performed his duties as consort by unveiling a plaque at the end of his visit to Richmond Adult Community College in Richmond, west London.

Born in Mon Repos on the Greek island of Corfu, Philip Mountbatten, the Prince Philip of Greece and Denmark was of the House of Schleswig-Holstein-Sonderburg-Glücksburg.

He moved to England in 1928 and enlisted in the Royal Navy, graduating from Royal Naval College, Dartmouth, in 1940.

The Queen appointed him Lord High Admiral of the Royal Navy -- the highest rank in the organisation other than the sovereign -- in 2011.
