Piers Morgan stormed off the Good Morning Britain set after getting into a clash with colleague Alex Beresford.
Beresford branded Morgan's behaviour 'diabolic', in the wake of comments made by the show's tempestuous anchor about Meghan Markle and Prince Harry following their recent interview with Oprah Winfrey.
Talking about the interview and the couple's decision to leave the UK to start a new life in the US, Beresford said: "They have had an overwhelming amount of negative press.
"I watched the programme yesterday and yes they had some great press around the wedding, but what press is going to trash someone's special day?
"There was bad press around the engagement, before the engagement and everything that has followed has since has been incredibly damaging, clearly, to Meghan's mental health and also to Harry."
Speaking to Morgan, he added: "I understand you don't like Meghan Markle, you've made it so clear a number of times on this programme and I understand that you had a personal relationship with Meghan Markle and she cut you off.
"But she's entitled to cut you off if she wants to - has she said anything about you since she cut you off? I don't think she has, yet you continue to trash her..."
At this point, Morgan stood up and said: "OK, I'm done with this," and began to walk off the set.
In response Beresford said his behaviour was 'pathetic', before adding: "This is absolutely diabolical behaviour.
"Piers spouts off on a regular basis and we all have to sit and listen. Six thirty to seven o'clock yesterday was incredibly hard to watch - incredibly hard to watch."
And Beresford isn't the only one unimpressed by Morgan's comments.
Yesterday mental health charity Mind released a statement condemning comments he made on yesterday's show (8 March), in which he implied he didn't believe Meghan had experienced suicidal thoughts.
In a statement the charity said: "We were disappointed and concerned to see Piers Morgan's comments on not believing Meghan's experiences about suicidal thoughts today."
"It's vital that when people reach out for support or share their experiences of ill mental health that they are treated with dignity, respect and empathy.
"We are in conversation with ITV about this at the moment."
On yesterday's show Morgan said he had been left 'sickened' by the interview and said he 'didn't believe a word' that Meghan had said, adding: "I wouldn't believe her if she read me a weather report."Featured Image Credit: ITV
