You'd think she could at least try to keep up with the Queen, who is 20+ years older than her. There are hundreds of charities that are turned down by other royals because they are too busy. She could easily pick up some of these charities that are desperate for a royal patron.
Here's the breakdown of the stats:
According to official Palace Court and Social records, Camilla carried out 137 domestic engagements and helped Charles on four foreign visits, while she pulled out of one Middle East tour because aides said she found it "too hot".
Last year, the Queen carried out 425 engagements and Prince Charles 498, thus making the Princess Royal as the hardest working royal with 613 official jobs and appointments.
However, many of Camilla's engagements were limited to attending family parties, joint visits with Charles, or receiving guests. In fact, one listed job was simply getting on a plane on the way to a trip overseas.
