A Buckingham Palace spokesperson confirmed that Princess Anne, 73, will instead watch the ceremony from Team GB House alongside representatives from the British Olympic Association (BOA).
This is part of Anne’s phased return to royal duties, and she will have a full schedule of visits supporting British athletes over the next few weeks of competition.
This decision follows the Princess’s recent hospitalization due to a concussion and minor head injury from a horse-related incident at her Gloucestershire home, Gatcombe Park, on 23 June. She spent five nights at Southmead Hospital in Bristol before being discharged.
On 12 July, she made her first public appearance since the accident by presenting awards at an equine competition at Hartpury University and Hartpury College in Gloucestershire.
In her first overseas trip during her recovery, Anne flew to Paris earlier this week to attend the 142nd International Olympic Committee (IOC) Session.
The Princess has been a member since 1988 and is also the president of the BOA. She was the first member of the British royal family to participate in the Olympics, competing in a three-day equestrian event on the late Queen’s horse, Goodwill, at the 1976 Montreal Games.
