The number and extent of the overseas visits undertaken by The Queen during her 60-year reign must be unprecedented: in her Silver Jubilee year alone, it was estimated that she travelled 56,000 miles. As Head of the Commonwealth, and accompanied by The Duke of Edinburgh, The Queen made two extensive tours in 1977 – the first to the Pacific Islands, New Zealand and Australia, the second to Canada and the Caribbean. The Queen is pictured here with The Duke of Edinburgh during the first of these tours.
