Queen Elizabeth II and husband Prince Philip mark their platinum wedding anniversary on Monday 20 November 2017. The couple married at London's Westminster Abbey 70 years ago, just two years after the end of World War Two, in a glittering ceremony which attracted statesmen and royalty from around the world and huge crowds of cheering well-wishers.

Seventy years on, no public events are planned and Elizabeth, now 91, and her 96-year-old husband will celebrate the milestone with a private party at Windsor Castle. However, the Abbey itself will mark the occasion with a full peal of its bells involving 5,070 change of sequences, with the 70 reflecting the anniversary, which will last more than three hours.
