Princess Anne believes the Queen was totally correct in her decision remain at Balmoral with Princes William and Harry in the days after Princess Diana's death.
The Princess Royal said her mother did "exactly the right thing" by not returning in the immediate aftermath of the fatal Paris crash in 1997.
Her absence from London, where millions had gathered to lay flowers and pay tribute to the late Princess, frustrated the public who questioned why the sovereign wasn't publicly mourning Diana.
