This Morning presenter Phillip Schofield has denied Kerry Katona was ‘ambushed’ during an interview which saw slurring her words and acting erratically.

Explaining the circumstances leading up to Wednesday’s interview – in which Kerry blamed prescription drugs for her slurred speech – Phillip said: “She arrived very late and didn’t give anyone any time to sit down and talk to her.

“She came through to the studio, we kissed her on the cheek and the programme went on air, so at no point had we any idea what condition she might be in.”

Phillip told BBC Radio 1 that Kerry had been upset by the interview and was ‘very, very angry with us and she got up and walked out of the studio with her husband’.

He stressed there was ‘no way that our producer would have allowed that interview to go ahead, had we known the situation she’d found herself in that morning’.

Phillip, who co-presents This Morning with Fern Britton, insisted: “The last thing I want to do is to witness a car crash in front of my eyes.”

Kerry’s husband, Mark Croft, later posted a statement online saying his wife’s slurring had been ‘particularly bad’ because she had taken her prescription drugs four hours late on Tuesday night.

“Kerry would like to categorically state for the record that that the only thing she drank before the show was cups of tea,” he added.

“Having answered the questions to the best of her ability, Kerry was upset at the insinuation that she was on anything other than the prescription drugs, which she has always been honest about taking.”

Kerry’s publicist Max Clifford told Sky News Online: “Had I been there I would not have allowed her to go on. There’s no way I would have let her go on for an interview if she was slurring very badly and, because of her history, a lot of people doubt that (it was due to her medication).
