Charles III was the oldest person to ever ascend to the British throne when he became king following his mother’s death.
At 73, he was almost a decade more advanced in years than the next oldest monarch when he finally became sovereign — William IV had become king aged 64 in 1830.
The Queen’s son — who had the longest wait of any heir in UK history — is likely to be concerned with more immediate occasions, such as his coronation at Westminster Abbey or his first overseas visit.
