Media captionArchive report: Princess Anne's first public appearance

The Princess Royal is celebrating her 60th birthday by spending time with her husband, Vice-Admiral Tim Laurence.

To mark the milestone, photographer John Swannell was commissioned to take an official portrait, as he had done to mark her 40th and 50th birthdays.

Princess Anne says she will not curb her busy lifestyle, having attended more than 600 engagements last year.

As well as backing many charities, the princess is on the organising committee for London's 2012 Olympics.

The second child of the Queen, Princess Anne has been president of the Save the Children Fund since 1970 and is president or patron of 320 organisations in total.

She has two children from her first marriage to Mark Phillips; Zara, 29, and Peter, 32, whose Canadian wife Autumn is expected to give birth in December.

However, in an interview with the BBC's Inside Sport programme, the princess played down suggestions that she might take her work down a gear once she becomes a grandmother.

"Look around at the members of my family who are considerably older than me and tell me whether you think they have set an example which suggests that I might - unlikely," she said.
