The Duke of Edinburgh, the longest-reigning consort in history, was married to Queen Elizabeth II for 73 years. As her husband, the Duke made sure Her Majesty was not disrespected and would become “incandescent” with anyone who took aim at her, according to royal biographer Gyles Brandreth.
The author told Mirror.co.uk: “For more than 70 years, he did everything he could to safeguard her person and her dignity.
“He hated to see her taken advantage of in any way.
“One year, at the Royal Variety Performance, one of the stars performed a routine aimed directly at the Queen.
“Prince Philip was incandescent and descended on the producer in the interval: ‘I’ve been coming to this for 50 years.
“It never ends on time. The jokes are lavatorial. And now you insult the Queen!’”
Mr Brandreth also recounted a time when Philip had to make way among a multitude of photographers for the Monarch.
He said: “More than once, on a walkabout with the Queen, I saw him barking at the press photographers, telling them to ‘get out of the way’.
“‘People want to see the Queen,’ he shouted, ‘Get out of the way!’”
