Prince Charles is not making a song or dance of his 69th birthday today as he celebrates the occasion in private.
Charles has now spent half a decade as the oldest heir to the throne for 300 years.
The Prince of Wales took on a symbolic duty on behalf of the Queen on Remembrance Sunday as he led the service honouring the nation’s war dead.
The king-in-waiting, dressed in military uniform, placed a wreath of poppies at the Cenotaph in Whitehall as the monarch watched from a balcony.
In a break with tradition, it was the first time Elizabeth II, now 91 and the nation’s longest reigning monarch, has not performed the symbolic duty when at the poignant service.
Gun salutes will fire in Green Park and the Tower of London, and at Edinburgh Castle in Charles’ honour.
The eldest child of the Queen and the Duke of Edinburgh, Prince Charles Philip Arthur George was born at Buckingham Palace on November 14, 1948, weighing 7lb 6oz.
He became heir apparent on the death of his grandfather King George VI, when his mother succeeded to the throne on February 6, 1952.
He was just three-years-old.
Charles became the Prince of Wales on July 26, 1958, when he was nine-years-old.
Before Charles, the oldest heir was Sophia of Hanover who died aged 83 in 1714.
He overtook William IV who became King in June 1830, aged 64.
Charles also passed the record for longest serving heir to the throne set by his great-great grandfather Edward VII, who became King aged 59 when Queen Victoria died in 1901.
