Prince William will deliver the keynote speech at this year’s Charity Commission annual public meeting, the regulator has announced.
The meeting, which will also feature the chair and chief executive of the commission, will take place at the Royal Institution in London on 23 January, the commission said.
Details of the prince’s speech have not yet been released, but a spokesman for him said the speech would be "sector-focused".
The prince will also meet charity representatives at the meeting, the spokesman confirmed.
The prince is patron of a number of charities. With his wife, the Duchess of Cambridge, and his brother Prince Harry he also directs his charitable activities through the Royal Foundation of the Duke and Duchess of Cambridge and Prince Harry.
Last year the foundation spearheaded the Heads Together campaign, which brought together eight mental health charities to raise awareness of mental health issues.
The prince has also campaigned prominently on issues relating to conservation and young people and is an active supporter of the armed forces and related charities.
The meeting will be chaired by William Shawcross, the chair of the Charity Commission, who is stepping down at the end of January. Shawcross has written the official biography of Queen Elizabeth the Queen Mother.
Helen Stephenson, chief executive of the Charity Commission, will also speak and answer questions from attendees at the meeting, the announcement from the commission said.
Last year’s annual public meeting saw a keynote address from the Prime Minister, Theresa May, in which she set out her vision for the "shared society".
