Countess Mountbatten of Burma, who survived the IRA bomb that killed her father, Earl Mountbatten, and her son, has died aged 93.

A statement from the family said: “Patricia Mountbatten died peacefully on Tuesday 13 June at her home in Mersham, Kent, surrounded by her children.”

A great-great-granddaughter of Queen Victoria and cousin to the Duke of Edinburgh, Lady Mountbatten’s life was devastated in August 1979 when the IRA blew up the family’s boat in Co Sligo.
