Princes William and Harry visit Princess Diana’s memorial garden

There was a time when such a scene would not have happened. There is the new novel, “Imagining Diana”, which speculates about what her life might have looked like if she had survived the auto accident that killed her.

She was 36 years old. “I love the semi-wildness”.

“Together, they will reflect on the significant achievements of the Princess and the legacy of her work, which continues to resonate with so many today”, a palace spokeswoman told Sky News.

The response though was not quite so generous at Buckingham Palace, with the Queen and her senior courtiers dismayed that a senior member of the Royal Family had become involved in such a controversial subject as AIDS which, at that time, was an incurable illness primarily associated with the gay community.

After their fairytale wedding in 1981 Diana and Charles chose Australia for their first official tour in 1983 – a trip that also caused angst for the princess.

“Imagine if Twitter or Facebook had been around in (Diana’s) day!” But trapped in a loveless marriage, Diana chose to take her message to the people who loved her. He said: “I don’t believe that being chased by 30 guys on motorbikes, who block your path, who spit at you, who shout at you and who react really badly to get a reaction from you and make a woman cry in public to get the photographs – I don’t believe that is appropriate”.

A midnight vehicle crash in Paris, exactly 20 years ago, had set in motion a chain of events that changed not only the Royal Family but Britain itself.

“She was talking about things which no princess had ever spoken about before”.

Diana dazzled Sydney’s social set at a glittering charity dinner for the institute, where pop star Sting serenaded her and hundreds of people lined the streets to catch a glimpse as she arrived.

Outside the palace, Britons left flowers of their own on Tuesday. Said a consultant to Burke’s Peerage, the Who’s Who of British aristocracy: “‘There can not be another family so stiff with royal connections'”. Not shedding a tear as thousands in the crowds wept.

It is a more muted affair than in 1997, when a sea of flowers formed outside the gates after Diana’s death.

Angela Silva, 66, has briefly left her London restaurant to leave a bunch of coloured roses, “not as big as the bouquet I left before, 20 years ago”, she says.

But the Duke and Prince appear to have dealt very differently with the emotional fallout following their bereavement, with William seemingly coping better with his feelings of “anger” while younger sibling Harry admitting to receiving professional help.

Both men beamed with smiles as they made their way through the garden entrance with the Duchess of Cambridge and saw the full floral display of gorgeous flowers – many of which were Diana’s favourites.

Harry told one group of campaigners that his mother’s death was a tragedy for them too. In an interview this year, William and Harry publicly credited her with teaching them not to suppress their emotions. We then put her in an ambulance.

As for the reason why they what the princess dead, the lawyer said it was because the princess was carrying Dodi Al Fayed’s child.

Prince William, the United Kingdom’s future king, wants his subjects to be able to be open about their emotions.

Diana also changed the public’s expectations of national figures, Cashmore said, noting that Britons are no longer satisfied with a distant monarchy. In the midst of all the celebrations, his two sons, William and Harry decided that it was time for them to confide this awful grief.

“The royals were always formal and stuffy and didn’t have a connection with the public”.

The gathering follows weeks of renewed interest in Diana, the first wife of heir-to-the-throne Prince Charles.
