London: By spending in wait for 59 years, two months and 14 days as heir apparent to the British throne, Prince of Wales broke the record of his ancestor Edward VII.

Before him Edward VII ascended the throne to succeed Queen Victoria, Britain's longest serving monarch after a wait of 59 years, two months and 13 days.

At the age of 62, Charles reached the milestone on Wednesday and his mother Queen Elizabeth is still in good health and celebrates her 85th birthday on Thrusday.

Charles became heir apparent at the age of three when his mother, Princess Elizabeth, ascended the throne on February 6 1952. He was nine when he was given the title of Prince of Wales.

The heir apparent is currently the eldest son of the sovereign unless the monarch's children are all female and his right to succeed cannot be altered.

Britain's Deputy Prime Minister Nick Clegg has said that the government is looking at the possibility of changing the rules of succession.

Changing the laws for Royal succession would require agreement across all 16 realms where the British monarch is the head of state.
