Prince Philip, 98, retired from official royal affairs two years ago. Since then, he has been enjoying his retirement and spending most of his time at Wood Farm in Sandringham, Norfolk. But while he enjoys many aspects of his retirement, there is a British hobby that he can not stand.
The Duke of Edinburgh was born in 1921 in the Greek and Danish royal families.
After a difficult childhood during which his family was exiled from Greece and lost several members of his family, he was educated in Britain.
The Duke married the Queen, then Princess Elizabeth in 1947.
When he married the Queen, he became a naturalized British citizen, but that did not mean that he was adopting all the customs.

Royal hotel owner Grant Harrold said in a BBC Three documentary that the monarch is also very sensitive to the way she prepares and drinks her tea.
He added that she usually serves it before the milk.
He told the BBC: "I'm sure the queen likes her Assam or Earl Gray in the traditional way, made with tea leaves in a teapot and poured into a soft porcelain cup.
"She will also use a colander.
"It's also a myth that royalty uses their little finger to drink, I have never seen it happen once."
Although Prince Philip is not adventurous with his tea, he would be more spontaneous and curious with his palette of dishes.
Unlike the queen, who is said to prefer simple or relatively bland dishes, Prince Philip is a foodie.
He would have even forced the palace staff to exchange dinners with him because he liked the look of theirs better.
Darren McGrady, a former chef at Buckingham Palace, told Marie-Claire: "He walked into the kitchen and said," What are we eating tonight?
"And I said, I have those little eyes of an inch of lamb for you, your Royal Highness.
He looked and said, "What is it, what are they? "
"And I said," Oh, these are chops, your highness. "He wanted to know who they were, and I said," the staff. "
And he said, "Oh, can not we have them? "
"I ended up giving him those bigger chunks, and the staff had the other pieces."
