Charles and Camilla married in a civil ceremony at the Windsor Guildhall on April 9, 2005 after a relationship which spanned nearly 35 years.
The Prince and the Duchess are spending their Tin wedding anniversary privately at Birkhall - their favourite retreat on the Balmoral estate in Scotland where they honeymooned and spent their first wedding anniversary.
Following requests a picture has been made available by Clarence House showing the royal couple relaxing at Birkhall. It was taken earlier this year and originally released to mark a CNN interview the Prince gave ahead of his US tour last month.
Royal author Penny Junor said Camilla has gained courage and confidence in her 10 years since joining the royals. Her role has changed dramatically. One minute she was a mistress and then she was an HRH,” Junor said. “When she first married Charles she was very nervous.”
But she said she had gained ‘courage and confidence’.
