Dermot O'Leary said it was difficult as he discussed Phillip Schofield's ITV exit.
Mr Schofield stepped away from the channel after he admitted to having an affair with a colleague. The 61-year-old conducted his first TV interview with the BBC's Amol Rajan and issued an apology.
He said: "I would say to everyone, to my family, my friends, my work colleagues, the public, to ITV, my management company, to everyone that I lied to, that I am desperately sorry." Dermot hosted today's This Morning as they discussed the interview.
