Meghan Markle's half-sister says paparazzi stressed out their father

Meghan Markle's half-sister said their father was under an "unbelievable" amount of stress because of media intrusion. Samantha Markle told the TV show "Good Morning Britain" on Tuesday that journalists "rented the house next to him in Mexico, four or five of them. He can't open his blinds, he can't go anywhere without being followed."

On Monday, Thomas Markle said that he won't attend his daughter's wedding to Prince Harry after he posed for embarrassing photos in exchange for payment from a paparazzi agency. Thomas told TMZ that he suffered a heart attack last week and will skip the wedding -- leaving open the question of who will walk the bride down the aisle.

He is not the first person to be bruised in the collision between Britain's royal family and the media -- a relationship that is deep, complex and sometimes toxic. 

"It is a symbiotic and parasitic relationship which is harmful to both sides," said Graham Smith of anti-monarchy group Republic, who is resolutely unaffected by royal wedding fever. "Certainly harmful to the British public in terms of the way in which we are fed this hype and nonsense ... and clearly harmful to the family."

For centuries, Britain's royal dramas played out at a distance from the public, as a deferential media protected the secrets of the monarchy. In the 1930s, the romance between King Edward VIII and divorced American Wallis Simpson was headline news in the U.S. press, but barely mentioned in Britain until the king abdicated, forced to choose between the crown and the woman he loved.

That changed by the time Prince Charles married 20-year-old Lady Diana Spencer in 1981 in a ceremony watched by hundreds of millions of people around the world. The media charted every twist in the saga that followed: the births of sons William and Harry, Diana's glamour and charity work, and her evident and growing unhappiness in the marriage.

Charles and Diana both used the media as a weapon as their marriage foundered, giving TV interviews to present themselves in a sympathetic light. It was ratings gold, reaching a peak when Diana told an interviewer that "there were three of us" in the marriage -- Diana, Charles and his paramour Camilla Parker-Bowles.

"Diana turned the royal family inside out," said Ellis Cashmore, honorary professor of sociology at Aston University and author of books on celebrity culture. "All the dirty secrets had come into the public domain."

Diana became the most famous woman on Earth, trailed by paparazzi wherever she went -- including to her death. She was killed in a Paris car crash in 1997, while being pursued by photographers.

Diana's death provoked a crisis for the monarchy -- portrayed as remote and cold at a time of national grief -- and for the media, accused of hounding a vulnerable woman.

In the years that followed, palace and press reached an uneasy truce. The royal family made concessions to popular interest, including carefully staged interviews and photo opportunities with William and Harry as they grew up. That practice has continued with the three young children of William and his wife Kate.

But Diana's sons retain a deeply ingrained mistrust of the media.

"Harry's attitude towards the press is he doesn't like the press," former Sun newspaper royal editor Duncan Larcombe, author of "Prince Harry: The Inside Story," told Town & Country magazine. "In Harry's mind, it was the press that killed his mother."

When Harry and Markle decided to make their relationship public, the prince fired a broadside at the media, saying that biracial Markle had faced "a wave of abuse and harassment," including "racial undertones" in comment articles.

"This is not a game -- it is her life and his," said the statement from Harry's press secretary.

Still, Markle's media experience, gained during her career as an actress, has been evident from the start. At the couple's televised engagement interview she appeared relaxed, confident and happy. It was a far cry from a 1981 interview with shy Diana and awkward Charles, who replied "whatever love means" when asked if he was in love.

Saturday's wedding is expected to draw more than 5,000 media staff and 79 television networks from around the world to Windsor. American and international TV networks plan hours of live coverage.

"I don't think anything can quite prepare her," Cashmore said -- though as "an independent-minded woman, brimming with confidence" Markle is well equipped to deal with intense media interest that is unlikely to fade.

"The media are the public's proxy," Cashmore said. "The reason they go for these stories that are ever more intrusive is that we want it."
