The royal couple will mark 70 years of marriage on November 20 - the first members of the famous family to do so - but they are not planning to hold a public event to celebrate the milestone because they are said to be content with having a "private affair".

A royal source told the Daily Express newspaper: "Any celebration will be a private, family affair.

"There will be no public event."

Elizabeth, 91, and Philip, 96, previously marked their silver, golden and diamond wedding anniversaries with national services of thanksgiving, which were held at London's Westminster Abbey.

While there will be no such event for the latest special occasion between the pair, double-headed platinum coins will be released to mark their 70th anniversary, and a new biography about them is to be released.

What's more, a tune, 'Royal Platinum Love Song', has been composed by Russian Olga Thomas, and features Australian tenor Daniel Koek and soprano Joanna Forest, to mark the event.

Olga said: "The queen and Prince Philip's relationship is inspirational for me.

"I love the idea of a traditional commitment which seems to be less common these days.

"They are symbols of everlasting love, a true reflection of what a marriage really should be, two people working together as one, a long-term commitment to each other and values that I hold dear."

Elizabeth and Philip tied the knot on November 20, 1947 at Westminster Abbey, and they received more than 2,500 gifts from around the world.
