In his controversial eulogy for his sister Diana, Earl Spencer blamed the princess's death on the paparazzi.

"It is a point to remember that of all the ironies about Diana, perhaps the greatest was this—a girl given the name of the ancient goddess of hunting was, in the end, the most hunted person of the modern age," he said.

It is another great irony that decades after her death, Diana's story remains a point of almost compulsive fascination for the public, and her innermost struggles and private agonies are the subjects of three new high-profile media events.
