The pair are among other famous faces expected to be invited to hand over information to an inquiry, which is looking into Phil’s affair with a young male runner.
The Sun on Sunday revealed it will take 12 weeks to complete.
A source told The Sun on Sunday: “The inquiry will speak to all those involved.
“It will focus on what happened before and after he was first given work experience on the set of This Morning. And it will also seek to establish who knew what and when.
“As well as speaking to current staff it will also invite former employees to come forward with information.”
They are likely to include Eamonn, Ruth Langsford and Dr Ranj — as well as production staff.
This Morning hosts Alison Hammond and Dermot O’Leary will also be interviewed along with Holly Willoughby.
Jane Mulcahy KC is leading the independent inquiry for ITV.
It was ordered by ITV boss Carolyn McCall after Phillip admitted lying to cover up his affair.
Schofield, 61 — pictured yesterday in Cornwall — and his former lover will be quizzed at length about their relationship.
But the report’s findings are unlikely to be published until the winter, according to sources.
And the investigation is only just about to get underway despite the intense focus on the case.
Dame Carolyn said the TV star had been quizzed over widespread rumours but admitted she failed to launch a formal investigation.
She branded the relationship “deeply inappropriate” and said only “ongoing reviews” were held. None of them established the full facts, she added.
She told the Culture, Media and Sport Committee she first became aware of a rumour about the relationship in December 2019, two years after she joined ITV.
Phillip and the runner — identified only as Person X — both “categorically denied” any affair.
Person X was asked 12 times, including twice with a human resources staffer present.
When asked if ITV had pressured him to remain silent, Dame Carolyn said: “I want to be clear it was Phillip putting him under pressure — not ITV putting him under pressure.
“They are two quite different things.”
Dame Carolyn denied the affair was an “open secret” at ITV.
ITV’s managing director Kevin Lygo said he confronted Phillips in February 2022 when he came out on This Morning and when he stepped down in May.
He added: “He looked me in the eye and promised me there was no truth to the rumours of this relationship. Because it was corroborated by Person X, I believed him and I believed his agent.
“Then two days later, he comes out and says, ‘No, it’s a lie’.”
Once the report has been put together, ITV will review the results and take action accordingly.
