Dame Carolyn McCall, the broadcaster's chief executive, faced questions on Schofield's departure from This Morning alongside managing director Kevin Lygo and general counsel Kyla Mullins, during a culture, media and sport committee session in parliament.

They told the hearing that both Schofield and the younger male colleague, referred to as Person X, "repeatedly denied" having a relationship until the presenter's shock admission in May, and pushed back against claims it was an "open secret" - as made by people including former Good Morning Britain presenter Piers Morgan.

ITV bosses questioned by MPs - as it happened

Dame Carolyn said bosses "were repeatedly told nothing was happening", and both men denied it "both formally and informally", with Person X being questioned on 12 occasions over a period of time.

"There was only hearsay and rumour and speculation," ITV's chief executive said. "Nobody on the board would have turned a blind eye to something as serious as this."

If evidence had emerged about the relationship, bosses "would have acted very swiftly", she said.

During the session, the ITV bosses also responded to allegations of a "toxic" environment on ITV's daytime shows, and faced questions about other issues such as the suicides of Love Island contestants and presenter Caroline Flack, and allegations about "abuse" and "bullying" on The X Factor.

The hearing was called after Schofield, 61, resigned from ITV and admitted to the "unwise but not illegal" affair which started when Person X was 20. The presenter was subsequently dropped by his talent agency, YMU.

Dame Carolyn told MPs that the "imbalance of power, the imbalance of dynamics" made the relationship "deeply inappropriate".

ITV bosses deny NDAs and gagging orders

The hearing was told the matter was looked into at around the time when Schofield came out as gay on This Morning in February 2020, supported by his then co-presenter Holly Willoughby.

Dame Carolyn confirmed Schofield has been "receiving counselling" since his exit from the show and that she is "very concerned" about his welfare.

She also confirmed there is "no gagging order or NDA" to stop Person X from speaking out about the situation, and denied he was given a "pay-off" when he left ITV. The hearing was told he received a standard redundancy payment.

The ITV bosses were also asked about how the young man came to work at ITV. MPs heard he applied for work experience and listed Schofield as a family friend, but this was not that unusual and the application did not ring "alarm bells".

Person X carried out work experience at This Morning for about two weeks when he was 19, and "impressed people" before he was later offered a longer-term fixed contract, the politicians were told.

Is there a 'toxic' culture at This Morning?

Later in the session, MPs asked about allegations of a toxic culture at This Morning, and Dame Carolyn described these as "deeply" disappointing.

She confirmed the show has received two complaints about bullying or harassment in five years, and said these were "both taken very seriously". One of these was from the show's former resident doctor Dr Ranj Singh, who raised concerns about "bullying and discrimination" and afterwards said he felt like he was "managed out" for whistleblowing.

"It deeply disappoints me but we do not recognise that at This Morning, we have tangible evidence to tell you where the vast majority of people at daytime at This Morning are extremely engaged and very motivated," Dame Carolyn said.

MP John Nicholson told the panel he had received many messages from employees past and present at ITV talking about the bullying culture at the broadcaster, with one describing daytime TV as "particularly toxic".

Dame Carolyn replied: "They're very disappointing to hear. Deeply distressing. I've said we've had two official complaints, both of them investigated - it does not fill me with anything but sorrow."

She also described comments from This Morning editor Martin Frizell as "foolish", after he referred to aubergines when asked about allegations of a "toxic" work environment on the programme.

"I think Martin has made a mistake, I think he knows he made a mistake, I don't think he intended to say that. It was a foolish comment; an ill-advised comment, I absolutely agree," she said.

An independent review into the facts by a barrister, commissioned by ITV, was also discussed during the hearing, with Dame Carolyn saying: "There will be things to learn."

The barrister will review complaints made since 1 January 2016, and consider whether steps taken to deal with them were "appropriate and adequate".

The review is expected to be completed by the end of September.

The session ended with chairwoman Dame Caroline Dinenage saying the committee wants to be confident that "ITV isn't letting star power and favouritism damage the lives or careers of those working there".

Dame Carolyn responded by saying that ITV takes "every allegation about our culture seriously, but I think it would be very wrong to depict ITV as having an issue".
