The Duchess of Cornwall visited the world's only surviving 17th century ship with the Prince of Wales - and joked that she would like to borrow it for the Queen's pageant.
Admiring the Vasa warship, which sank on its maiden voyage in Stockholm, Sweden, in 1628, Camilla told King Carl XVI Gustaf: "It is very nice. Perhaps we could borrow it for the jubilee pageant."
She added: "It would be very nice going down the Thames."
The royal party was given permission to take a closer look and took a keen interest as museum staff gave them a guided tour.
