" On Friday, 3 December1993, at a charity luncheon in aid of the Headway National Head Injuries Association, the Princess announced her withdrawal from public life. In a sometimes quavering, yet defiant, voice she appealed for ‘time and space’ after more than a decade in the spotlight. During her five-minute speech she made a particular point of the unrelenting media exposure: ‘When I started my public life 12 years ago, I understood that the media might be interested in what I did. I realized then that their attention would inevitably focus on both our private and public lives. But I was not aware of how overwhelming that attention would become; nor the extent to which it would affect both my public duties and my personal life, in a manner that has been hard to bear.’
As she later said: ‘The pressure was intolerable then, and my job, my work was being affected. I wanted to give 110 per cent to my work, and I could only give 50…I owed it to the public to say “Thank you, I’m disappearing for a bit, but I’ll come back.”’
Indicating that she would continue to support a small number of charities while she set about rebuilding her private life, the Princess emphasized: ‘My first priority will continue to be our children, William and Harry, who deserve as much love, care and attention as I am able to give, as well as an appreciation of the tradition into which they were born.’
While she singled out the Queen and the Duke of Edinburgh for their ‘kindness and support’, Diana never once mentioned her estranged husband. In private, she was unequivocal about where the blame lay for her departure from the stage. ‘My husband’s side have made my life hell for the last year,’ she told a friend.
When she reached the relative sanctuary of Kensington Palace that afternoon, Diana was relieved, saddened but quietly elated. Her retirement would give her a much-needed chance to reflect and refocus. If the separation had brought her the hope of a new life, her withdrawal from royal duties would give her the opportunity to translate that hope into a vibrant new career, one that would employ to the full her undoubted gifts of compassion and caring on a wider, international stage.
A few months later, at a reception at the Serpentine Gallery, of which she was patron, the Princess was in fine form. She was relaxed, witty and happy among friends. The events of 1993 seemed a dim and dismal memory. As she chatted to the movie star Jeremy Irons he told her: ‘I’ve taken a year off acting.’
Diana smiled and replied: ‘So have I. "
