Andrew Mountbatten-Windsor is closing down some of his last remaining known business interests, including Pitch@Palace Global Ltd.
Pitch@Palace was a Dragon's Den-style start-up competition where entrepreneurs could present their ideas to potential investors, and was once seen as a possible source of income for the former prince, after the King stopped supporting him financially.
A document announcing the application to dissolve the company was filed with Companies House on Tuesday, signed by the company's only director Arthur Lancaster.
Mr Mountbatten-Windsor and Mr Lancaster have been approached for comment.
