Ben Shephard stepped in for Piers Morgan for the first Good Morning Britain Monday show since the controversial presenter quit last week.
Piers, 55, stormed off set last week after an on-screen row with co-star Alex Beresford.
Ben usually co-presents Good Morning Britain on Thursdays, but joined Susanna Reid in the studio today.
Piers will not be returning after he refused to apologise for saying he did not believe Meghan Markle's claims that she had felt suicidal, which she made in an interview with Oprah Winfrey.
After the announcement of his exit, Piers tweeted that he had "trusted his gut" and this morning defiantly said that he still did not believe the Duchess of Sussex had suffered from suicidal thoughts and that "freedom of speech is a hill [he] is happy to die on".
He had previously laughed off an online petition, which had been signed by 92,000 people, to get him sacked from his position.
Mental health charity Mind, who work on ITV's Get Talking campaign, also came out against the combative host and said that they were "disappointed" by his remarks.
ITV released a statement regarding his departure, stating: "Following discussions with ITV, Piers Morgan has decided now is the time to leave Good Morning Britain. ITV has accepted this decision and has nothing further to add."
However, the Mirror has since revealed that Piers is currently at the centre of a £10million bidding war between Murdoch and GB News.
Piers, on an estimated £3million a year at ITV, may front Rupert Murdoch’s upcoming “opinionated” News UK TV venture or become a star feature of his US network, Fox News.x Beresford, who branded his views on Meghan Markle "diabolical".
