The Princess Royal has brought together fellow British athletes who took part in both the 1976 Games at a special reception at the Lansdowne Club in London, 50 years after competing at the Montreal Olympics.
Acting in her role as Patron of the GB Olympians Association, King Charles's younger sister welcomed competitors who had represented Britain at the Innsbruck Winter Games and the Montreal Summer Games that same year.
The gathering celebrated the shared achievements and memories of those who wore the British colours half a century ago.
It was a unique opportunity for athletes from both the winter and summer competitions to reconnect and reflect on their Olympic experiences.

Princess Anne, 75, became the first member of the Royal Family ever to participate in the Olympic Games when she competed in Montreal.
She rode Goodwill, a horse belonging to her late mother Queen Elizabeth II, in the three-day eventing competition.
Although she did not secure a medal in Canada, the Princess Royal had already proven herself a talented rider on the international stage.
Her achievements included taking individual gold at Burghley in 1971, followed by individual and team silver medals at Luhmuhlen four years later.

These successes demonstrated her credentials as a serious competitor before her historic Olympic appearance.
The Princess Royal's connection to the Olympic movement extends well beyond her time as a competitor.
She holds the position of President of the British Olympic Association and has been a member of the International Olympic Committee since joining in 1988.
Between 1990 and 1994, she contributed to the IOC's Eligibility Commission.

Her leadership in equestrian sport at the highest level saw her serve as President of the International Equestrian Federation from 1987 to 1993.
These roles reflect her sustained commitment to international sport and Olympic governance over nearly four decades since her own competitive days ended.
The equestrian tradition runs deep within the family, with Princess Anne's daughter Zara Tindall, 45, following in her mother's footsteps by competing in the same discipline at the 2012 London Olympics.
Mrs Tindall claimed a silver medal as part of the British eventing team at those home Games.

Her father, Captain Mark Phillips, 77, who was previously married to the Princess Royal, enjoyed his own Olympic triumphs in the saddle.
He won team gold at the 1972 Munich Games and added team silver 16 years later in 1988.
The family's combined Olympic achievements in eventing span more than four decades of competition at the highest level.
