The 91-year-old monarch and her husband married in a ceremony at Westminster Abbey on November 20 1947, and on Monday (20.11.17), they celebrated reaching a whopping 70 years of married life together.

To commemorate their special day, the pair have posed for a new portrait in the the White Drawing Room at Windsor Castle, where they are framed on either side by portraits painted in 1781 of George III and Queen Charlotte, who were married for 57 years - the longest royal marriage until their own.

In the photograph - which was snapped by Matt Holyoak of the Camera Press, which is also celebrating its 70th year - Queen Elizabeth is wearing a a cream day dress by Angela Kelly, accompanied by a gold, ruby and diamond brooch Prince Philip gave her in 1966.

The Duke of Edinburgh, meanwhile, is wearing a tweed jacket and burgundy tie.

The commemorative portrait was revealed on Sunday (19.11.17), one day before their official anniversary, and on the same day, an interview was aired with Queen Elizabeth's cousin Prince Michael of Kent, who served as the pageboy at her wedding.

Speaking to soprano Katherine Jenkins on 'Songs of Praise' on BBC One, the 75-year-old royal recalled the "exciting moment" he saw his older cousin walk down the aisle.

He said: "It was a very exciting moment. It was in November, just after the war when everything was very grim and there wasn't very much to brighten up people's lives. So suddenly they had this tremendous, exciting service and it was something that radiated in people's lives."

Michael - who was just five when he took part in the ceremony - also recalls the "daunting" task of being the pageboy at the important event.

He said: "It was quite daunting because first of all the train was very heavy and it was quite a long way to go all the way down the Abbey, so one had to behave properly. I behaved particularly well. And going round corners was complicated, not treading on it was complicated, I seem to remember, and then one had shoes with buckles on."
