NEWSREEL Paramount News brings you a special coverage of Princess Ann's visit to London, the first stop on her much publicised goodwill tour of European capitals. She gets a royal welcome from the British as thousands cheer the gracious young member of one of Europe's oldest ruling families. After three days of continuous activity and a visit to Buckingham Palace, Ann flew to Amsterdam where Her Royal Highness dedicated the new International Aid Building and christened an ocean liner. Then went to Paris where she attended many official functions designed to cement trade relations between her country and the Western European nations. And so to Rome, the eternal city, where the Princess' visit was marked by a spectacular military parade highlighted by the band of the crack Piersa Yeri Regiment. The smiling young Princess showed no sign of the strain of the week's continuous public appearances. And at her country's embassy that evening, a formal reception and ball in her honor was given by her country's ambassador to Italy.
