The Duke of Cambridge will give the keynote speech at this year's meeting of the Charity Commission.
William will address delegates at the Royal Institution in London's Mayfair before meeting charity representatives.
The commission, which is the registrar and regulator of charities in England and Wales, said its annual public meeting is an important part of its commitment to public accountability and transparency.
