The Queen and Prince Philip are about to celebrate their 70th wedding anniversary. Their union is, rather impressively, the longest royal marriage in recorded history. With this in mind, it's rather unsurprising that 20 November 2017 is attracting a lot of attention. In fact, Russian composer Olga Thomas sees their platinum anniversary as so important that she's written a love song to mark the occasion. Proceeds from the track - which features a 72-piece orchestra and vocals from Daniel Koek and Joanna Forest - will raise money for Cruse Bereavement Care. The Queen is a patron for this charity. We think all newlyweds can learn a thing or two from the Queen and Prince Philip so we've rounded up their cutest ever quotes about each other.
