Prince Charles and Princess Anne have been named as the hardest-working members of the Royal Family, after undertaking over 600 official engagements each in 2003. Charles turned out for 494 events in Britain, beating both the Queen and his younger sister. But with foreign events taken into account, the Princess Royal leads the field, clocking up a staggering 624 appearances, compared to Charles' 604.
As the figurehead for a number of international charities, Anne generally has more foreign duties than the rest of the Windsors. In 2003, these included a two-week trip to America and Mexico in her capacity as President of Save The Children.
The Prince of Wales was also busy, though most of his duties were closer to home. It is well-known Charles often goes without lunch, as he prefers to attend three engagements a day whenever possible.
Despite giving birth to her first child, Sophie Wessex made a respectable showing, with 179 official engagements. So did her husband Prince Edward, who turned out for 412 events. Meanwhile the Duke of Edinburgh had 456 outings. They were both outdone by the Queen, however, as Her Majesty chalked up a total of 478 appearances.
