As a six-year-old growing up in Paris, Prince Philip often arrived at school half an hour early. While he waited for his fellow pupils, he spent the time cleaning blackboards, filling inkwells, straightening the classroom furniture, picking up litter and watering the plants. 

It was his British nanny, Emily Roose, who inspired such behaviour, instilling in him from a very young age a strong sense of duty. And although he would shortly afterwards move to Britain for the rest of his education, his early dedication to public service remained. More than 90 years later it is undimmed.

In 2016, the year of the Queen’s 90th birthday, she was asked to present the trophies on Derby Day. After the big race at Epsom, the Monarch took her place as those connected to the winning horse mounted the dais one by one.

Throughout the ceremony, her 94-year-old husband was standing upright as always, slightly to one side of the Queen. He was impeccably dressed in a morning suit with a grey top hat and a colourful green-and-maroon tie.
