The Boomtown Rats frontman was left devastated in March when the 25-year-old star died from a heroin overdose and he admits her passing makes him feel like he "failed" as a father.

He said: "She was super bright, too bright. She knew what life was supposed to be and God bless her, she tried very hard to get there and she didn't make it.

"I'm not just blaming the newspapers, of course not. You blame yourself. You're the father who's responsible and clearly failed."

Though the 63-year-old musician admits he did "more than talk about" Peaches' problems with her, Bob - who raised Peaches and her sisters Fifi, and Pixie and half-sister Tiger following the death of their mother Paula Yates from an overdose in 2000 - feels he could have done more.

He told ITV News: "For anybody watching, who has a dead kid and you're a parent, you go back, you go back, you go back, you go back, you go back, you go over, you go over, what could you have done."

And Bob admits he has still not been able to accept his daughter - who had sons Astala, two, and Phaedra, 17 months, with husband Thomas Cohen - is gone.

He said: "The ability to try and understand or to try to come to terms with the immensity of the grief is there but it takes a long while for it to filter through.

"I'm not there with Peaches yet. It was all too soon. It was all too sudden. It was unexpected."
