Last year she was forced to pull out of several engagement as she broke her wrist during a fall.
Despite her age, Princess Alexandra remains patron to around 100 organisations and the year prior she undertook around 82 engagements with the queen.
Although she is 50th in line to the throne, Princess Alexandra was known for her glamorous appearances including when she was The Queen’s bridesmaid.
Princess Alexandra is not the only member of the royal family to pull out of Princess Eugenie’s wedding.
The Duchess of Cornwall has also pulled out due to a prior commitment.
Instead Camilla Parker Bowles will conduct an engagement held at a school in Scotland.
“When this date was proposed, she said that regrettably, she couldn’t come,” a source told The Sun.
“The family understood, particularly Eugenie, and were fine about it owing to her previous commitment. Camilla didn’t want to let anyone down.”
