Aberdeenshire , Scotland ( CNN ) In an exclusive interview ahead of his U.S. tour -- and ahead of his 10-year wedding anniversary -- Prince Charles paid tribute to the `` brilliant '' way his wife , Camilla , Duchess of Cornwall , has taken on the `` real , real challenge '' of defining her public role . `` It 's always marvelous to have somebody who , you know , you feel understands and wants to encourage . Although she certainly pokes fun if I get too serious about things . And all that helps , '' Prince Charles told CNN . The couple first visited the U.S. together as newlyweds in 2005 , and Camilla was confronted by hardcore Princess Diana fans with abusive placards . Polls at the time found that between 57 % and 73 % of Brits opposed Charles ' new wife being known as queen . If you go back even further , to 1997 , the year Diana died , an Ipsos MORI poll put it at 86 % . Reporter 's notebook : Interviewing the royal couple . But there 's been a change in sentiment since they married . A new poll conducted by Comres for CNN found that only 35 % now oppose Camilla being known as queen . Nearly one in four said they liked her more now than they did 10 years ago . This coincides with a change in palace strategy -- away from the aggressive spin machine of the 1990s to simply allowing Camilla to be herself . When she appears in public , she 's either seen supporting her husband or promoting a set of causes she has a genuine connection with . Prince Charles praised how his wife has handled herself . `` She 's done an enormous amount for the whole issue around osteoporosis , which of course runs in her family , '' he said , noting that Camilla 's mother and grandmother both suffered from the bone disease . He also points to other issues Camilla is associated with , including literacy and preventing sexual violence . The Duchess of Cornwall , by sticking to what she knows and cares about , is able to connect with the people she meets , which does n't always come across on camera . When Charles and Camilla married in 2005 , there was huge sensitivity around the legacy of Diana , who was expected to be queen herself . With this in mind , royal aides announced that Camilla would not use the title of Queen when Charles becomes King . Instead she would be known as Princess Consort . That still stands , although the public of today looks less likely to oppose the title of Queen .
