ITV bosses have said both Phillip Schofield and the man he had an affair with "repeatedly denied" allegations of a relationship.
The broadcaster's chief executive Dame Carolyn McCall faced questions from MPs alongside ITV managing director Kevin Lygo and general counsel and company secretary Kyla Mullins about Mr Schofield's exit during Wednesday morning's Culture, Media and Sport Committee session in Parliament.
Dame Carolyn told MPs the "imbalance of power, the imbalance of dynamics" made the relationship "deeply inappropriate", and ITV would have taken action, but no evidence of the relationship appeared during on-going reviews.
