First British monarch to celebrate platinum wedding anniversary is pictured with her husband at Windsor Castle.

The Queen and the Duke of Edinburgh have been pictured in three more photographs as part of a series of portraits released to mark their 70th wedding anniversary.

The photographs, taken by British photographer Matt Holyoak, show Elizabeth II and Prince Philip in the White Drawing Room at Windsor Castle in early November.

In the latest sequence of pictures, released on Sunday, the royal couple are photographed against a platinum-textured backdrop.

One shows the Queen beaming as she sits on a golden chair with matching upholstery with her hands resting on her lap, and the duke standing next to her with his left hand in his pocket.
