Anne has become known as one of the Royal Family‘s hardest working members. Over the years, her intense work ethic has seen her travel both the UK and the world. This week, social media footage appeared to show the royal touching down in Plymouth to carry out yet more official duties.

Her ‘get on with it’ attitude has reflected in her personal relationships with both the media and members of the Firm.

She had a particularly frosty relation with Diana, Prince Charles’ former wife.

Diana entered the royal fold along with Sarah Ferguson, Prince Andrew’s ex-wife, and changed the face of the family from the inside out.

Their bad blood was explored during Channel 5’s documentary, ‘Paxman on the Queen’s Children’.

Here, royal author Richard Kay said: “Princess Anne, she had no time for Diana.

“She didn’t like the way she went about her duty and the way she used the cameras and the media to promote herself, in her eyes.

“Anne had a much more traditional approach to monarchy and royal duty.”

The programme’s presenter, former BBC journalist Jeremy Paxman, suggested that Anne’s aversion may have been rooted in Diana’s modernity.

It was 1981, and Zara Tindall had not long been born.

In two months’ time, Diana and Charles would marry at St Paul’s Cathedral.

Yet, controversy had already struck their relationship after Charles gave Camilla Parker Bowles – his former love interest and later wife – the now famous bracelet inscribed with the initials “F” and “G” – their nicknames for each other.

Reports suggest Diana was aware that Camilla would be present at the christening as her husband, Andrew Parker Bowles, was Zara’s godfather.

Royal author Ingrid Seward recounted the awkward moment in her 1995 book ‘Prince Edward‘.

She wrote: “Such occasions are a cornerstone of the Royal Family’s routine, and essential part of the theatricality of their brand of monarchy; a moment when the whole family is on parade.

“It would never have occurred to Edward or any of his family not to turn out for one.

“Diana, however, chose not to attend.

“She had been telling friends beforehand that she had no intention of going but, rather through a failure of manners or courage, it was not until 48 hours before the actual ceremony that she telephoned Princess Anne to inform her that she would not be there.

“Her excuse was that she was too busy preparing for the wedding ball that was being held in her honour that night.

“The tone of Anne’s response would have chilled the Arctic.”
