The Queen Mother has told aides she is determined to attend her daughter Princess Margaret's funeral, it is reported.
Doctors are concerned the 101-year-old Royal Matriarch may not be strong enough to make the journey from Norfolk to Windsor on Friday.
It is hoped she will be able to leave the Queen's Sandringham estate on Wednesday and have time to recover from the trip before the funeral.
Prince Charles has vowed to be at his grandmother's side as she bids farewell to her daughter, the Sun reports.
No decision on whether she will be at St George's Chapel on Friday afternoon will be made until the last minute.
Earlier she said private prayers for her younger daughter at Sandringham.
It was the Queen who broke the news of Margaret's death to the Queen Mother, who has been ill since Christmas with a persistent, chesty cold.
Although shattered by the death of her daughter, the elderly Royal is thought to be coping with the bereavement.
