The King and Queen will meet the new Pope during a state visit to Vatican City next month.
The couple will join Leo XIV , who was elected pope earlier this year after the death of Pope Francis, in late October to celebrate the 2025 jubilee year, Buckingham Palace said.
The Catholic Church typically marks a papal jubilee every 25 years.
Charles and Camilla 's visit is expected to celebrate the ecumenical work by the Church of England and the Catholic Church, reflecting the Jubilee year's theme of walking together as "Pilgrims of Hope".
The King is Supreme Governor of the Church of England, a role which dates back to Henry VIII, who named himself Supreme Head of the Church of England after he was excommunicated by Pope Paul III and broke from the Catholic Church in the 16th
