Why don't we see or hear anything about Princess Margaret anymore?

The Princess Posh, Duchess Of Pooch isn't trolling she's telling you the truth. Princess Margaret died in 2002.

God Rest HRH's Soul

She died a few weeks before her mother died,9 February 2002, and this was World News; it's a bit surprising that you don't know! The Queen lost her only sister and her mother in a matter of weeks.

Her funeral was held on 15 February 2002—the 50th anniversary of her father's funeral. In line with her wishes, the ceremony was a private service for family and friends.Unlike most other members of the royal family, Princess Margaret was cremated, at Slough Crematorium. Her ashes were placed in the tomb of her parents, King George VI and Queen Elizabeth The Queen Mother (who died seven weeks after Margaret), in the King George VI Memorial Chapel in St George's Chapel, Windsor Castle, two months later.

She's taken up permanent residence at St Georges Chapel Windsor Castle.

Most sensible people know that Princess Margaret died,

That is why we don't "see or hear" anything about her.

There is about as much to report in the news about her as when she was alive, nothing. All she did was take drugs and drink, occasionally opening the odd place to justify her snout being in the trough but that's it. Didn't she live remarkably long for a drug addict? How many really make it past 70?

Well, that's what happens when you're dead. As she has been for the last 13 years.

She did 'disappear off the face of the earth'. As said, she died a good many years ago now.

Died: February 9, 2002, London

There's very little to hear about. She's been dead since 2002.

She's making a comeback: she's got another three feet to go.
