The debate will take place at ITV's White City studios.
ITV will hold a live television debate with the Conservative leadership candidates next Sunday at 7pm.
In 2019, ITV's Conservative leadership debate between Boris Johnson and Jeremy Hunt was watched by 4.4 million viewers.
Michael Jermey, ITV's Director of News and Current Affairs said, "Television debates at important elections help voters engage with politics. ITV has been the home of some of the biggest political debates over the past decade. Sunday's debate will be an important event as the country's next Prime Minister is chosen."
