I don't think HRH Princess Anne would want the job, remember she did not want her children to be saddled with a royal title, she does a sterling job representing the Queen but I feel she would not want it as a full-time position.
Howard, openings in the royal household will be advertised at a later date, so keep your calendar open
On a seperate note after watching the Dispatches programme on Ageism within the job marketplace last night, it is indeed very worrying for the over fifties today who are looking for work.
