Princess Margaret Special



Britain's Queen Elizabeth has declared a period of royal mourning for Princess Margaret, her younger sister, who died at age 71.

Princess Margaret died "peacefully in her sleep" at 6:30 a.m. Saturday (1:30 a.m. ET) after suffering a stroke, Buckingham Palace announced. Her children, Lord Linley, 40, and Lady Sarah Chatto, 37, were at her side.

The palace said Princess Margaret suffered a stroke Friday afternoon and developed cardiac problems during the night. She was taken to the hospital at 2:30 a.m. Saturday.

Her body was moved to Kensington Palace Saturday afternoon in a coffin draped with her personal standard and an arrangement of white lilies.

Margaret's mother "has been told of the sad news of the death of Princess Margaret and she is deeply saddened," according to a statement from the queen mother's official residence, Clarence House.

Prince Charles described Princess Margaret as his "darling aunt" and said it had been "a terribly sad day" for the royal family.
