THE Princess of Wales returned to work at Windsor Castle just days after revealing she had completed her chemotherapy.
Kate, 42, held her first official meeting in more than nine months hosting a chat with early years charity chiefs.
Last week the princess revealed she had completed her treatment and was set to appear at a handful of engagements before the end of the year.
The official Court Circular, which lists all royal engagements, will read today: "The Princess of Wales, Joint Patron, The Royal Foundation of The Prince and Princess of Wales, this afternoon held an Early Years Meeting at Windsor Castle."
There were no photos of the meeting but it is understood she was joined by members of her household team and representatives from the The Royal Foundation Centre for Early Childhood.
Kate launched the centre in June 2021 to drive awareness of and action on the extraordinary impact of the early years, in order to transform society for the future.
