A man accused of killing his six children in a house fire has told a court he did not start the blaze but that he has his suspicions about who did.
Mick Philpott, 56, denied any involvement in starting the fire at his home in Victory Road, Allenton, Derby, in the early hours of May 11 last year.
Jade, 10, John, nine, Jack, eight, Jesse, six, and Jayden, five, died during the blaze. Their brother Duwayne, 13, was taken to Derby Royal Hospital and transferred to Birmingham Children's Hospital but died three days later.
Taking the witness box at the start of his defence case at Nottingham Crown Court, Philpott said he had nothing to do with the blaze.
Anthony Orchard QC, defending Philpott, asked him: "Do you know who did?" to which he replied: "No."
"Do you have your suspicions?"
"I do," Philpott answered.
Philpott, who along with his 31-year-old wife Mairead and a third defendant, 46-year-old Paul Mosley, denies six separate counts of manslaughter, told the court he regretted appearing on TV's Jeremy Kyle Show with his family.
He said: "We all decided. At that time we needed a bigger house."
The court heard that the children were bullied following their appearance on the programme, and Philpott said he and his children received death threats following the family's TV appearance.
