The Queen and the Duke of Edinburgh's engagement was celebrated 70 years ago at Buckingham Palace.
On July 10, 1947, Princess Elizabeth and Lieutenant Philip Mountbatten, as they were then known, were pictured arm in arm at the royal residence to mark the official announcement.
Elizabeth was just 21 and Philip, who had renounced his Greek royal title and become a naturalised British subject, was 26.
The beaming princess was wearing her elegant, square cut diamond and platinum engagement ring which the groom had had made using stones from one of his mother's tiaras.
A delighted looking Philip, who served in the Royal Navy during the Second World War, was dressed in his smart naval suit for the engagement photos. The Queen and Philip will celebrate 70 years of marriage in November.
