The Princess of Wales made an unannounced public appearance on Tuesday evening as she joined King Charles III and Queen Camilla at a reception marking the 125th anniversary of Cancer Research UK.
Held at St James's Palace, the event brought together researchers, clinicians, volunteers and campaigners involved in cancer research and treatment. The appearance was Catherine's first public engagement since her two-day visit to Italy in May and comes as she continues a gradual return to public duties following her cancer diagnosis and treatment.
