Queen Elizabeth and the Duke of Edinburgh arrived at Copenhagen's Kastrup airport, Oct 21, for a five-day private visit as guests of King Frederik and Queen Ingrid of Denmark. They flew in an RAF Comet from Lacashire where the Queen had earlier launched Britain's first nuclear submarine.

Denmark's King and Queen, with their 16-year-old daughter, Princess Benedikte, were waiting at the airport to welcome their guests. Queen Elizabeth, wearing a powder grey coat and a close-fitting feather hat to match, was greeted with a kiss on the cheek by King Frederik and Queen Ingrid. As if to stress the informality of the occasion, King Frederik was wearing a light fawn raincoat. Queen Ingrid wore a dark brown suit and matching hat.

The Queen and the Duke are staying with their hosts at Fredensborg Castle, about 25 miles north of Copenhagen, where they relaxed after their State visit in the spring of 1957. "The Queen fell in love with the castle," said an officer of the Royal Guard. "She said she would like to come and see how it looks in the autumn." King Frederik remembered her wish and extended a private invitation. He has left the programme for his guests entirely open.
