The presenter collapsed on Wednesday evening

According to the MailOnline, the TV presenter had been eating at a Pizza Express in Sunningdale on Wednesday evening (November 27) when he collapsed in front of other diners.

An ambulance was called for him and he was taken to Frimley Park hospital in Camberley, Surrey.

His representatives said Mulhern had undergone that a procedure earlier that day which required anaesthetic. When he had "a few drinks" that evening, he started to feel unwell.

The Deal or No Deal presenter recently took some time off from work following the death of his father.

A spokesperson told the Mail: "Stephen has had an incredibly tough time over the past few weeks. His beloved father recently passed away which has hit him hard and has been understandably very stressful.

"In addition he had a procedure which took place yesterday (Wednesday). Following the anaesthetic that was administered, he had a few drinks which made him unwell and he was."

A source also told The Sun: "He’s also been battling several well-documented health problems, and on Wednesday morning had a procedure requiring a local anaesthetic.

"He took himself off for a quiet, solo dinner that evening, had a few drinks and just reacted incredibly badly. He’s only human, and his dad’s death has hit him hard.

"Stephen immediately felt unwell and concerned staff came over, and called 999. Paramedics checked him over and took him to hospital as a precaution. He was also put on the phone to his mum to reassure her that he was OK."

The source added that Mulhern is "recovering well at home now" and is "so grateful for the care he received."

One of TV's most recognisable faces, Mulhern started out in the industry in the late 1990s. He became a popular figure on children's TV channel CITV, and has since gone on to present shows such as Britain's Got More Talent, Catchphrase, Deal or No Deal and Dancing on Ice.
