The Princess of Wales is making a gradual return to her royal duties amid her recovery from cancer, and next week she'll appear at a major event she missed last year.
Kate and her husband, Prince William, will join the King and Queen, the Princess Royal and the Duke and Duchess of Gloucester at the Commonwealth Day service at Westminster Abbey in London on Monday 10 March.
It's an annual celebration observed by millions across the Commonwealth in Africa, Asia, the Caribbean and Americas, the Pacific and Europe.
This year’s Commonwealth Day theme is Together We Thrive, which celebrates the "enduring spirit of the Commonwealth family".
Charles, who is Head of the Commonwealth, gives an annual address each year to the family of 56 nations, but last year pre-recorded a video message after postponing his public-facing duties for around three months.
Both Kate and Charles missed the key event in the royal calendar last year after being diagnosed with cancer.
At the time, the Princess's cancer diagnosis was not known but Kate was also recovering from major abdominal surgery she underwent last January.
Queen Camilla and Prince William led the royals at the service last year, and just weeks later on 22 March, Kate revealed in a shock video message that she was undergoing chemotherapy after post-operative tests showed she had cancer.
The Princess completed chemotherapy in September last year, and confirmed in January she is in remission from the disease.
She has carried out a number of engagements this year as she continues her return to public life, including visiting Pontypridd ahead of St David's Day last week.
Kate also marked Holocaust Memorial Day, visited Tŷ Hafan Children's Hospice, joined schoolchildren at the National Portrait Gallery in support of her Shaping Us Framework initiative and visited a mother and baby unit at HMP Styal in Cheshire.
