A judge said she would sentence Mick and Mairead Philpott on Thursday for their manslaughter convictions in the deaths of Jayden, Jesse, Jack, John, Jade and Duwayne, aged 5 to 13.
Prosecutors said the couple hatched a plan to start a gasoline-fueled fire and then rescue the children, pinning blame on Philpott's mistress so he could gain advantage in their child custody battle.
The plan went wrong within minutes, because the fire was far bigger than expected and the father was unable to smash a window to get in, prosecutors said.
The couple and a friend who helped them, Paul Mosley, were all convicted of manslaughter this week at England's Nottingham Crown Court.
Before the fire, Philpott, now 56, was a local celebrity nicknamed "Shameless Mick" after a television program about a disreputable working-class clan who had appeared on a daytime talk show defending his lifestyle. In 2007, a Conservative lawmaker stayed at his home for a week as she filmed a critical documentary about Britain's welfare system.
The jury and the nation got a close-up look during the trial at Philpott's messy life with his 32-year-old wife, his girlfriend and as many as 11 children in a three-bedroom social housing property in Derby, central England. They heard of his threesomes and public sex, of Philpott's controlling behavior and of his bizarre claim that he had not washed for 12 weeks before the fire.
Shortly before the fire, girlfriend Lisa Willis moved out, taking her five children with her. Philpott's five children with Mairead and his wife's 13-year-old son from a previous relationship remained in the home and died in the blaze.
After the fire, the Philpotts made an emotional appeal on television, with Mick describing how he had battled the flames to try to save his children.
But police soon grew suspicious of the couple's erratic behavior and bugged the hotel room where they were staying. The jury was played recordings of Philpott asking his wife: "Are you sticking to the story?"
The couple was arrested two weeks after the fire and charged with murder, later downgraded to manslaughter.
"It was started as a result of a plan between the three of them to turn family court proceedings in Mr. Philpott's favor," said Crown Prosecution Service adviser Samantha Shallow. "It was a plan that went disastrously and tragically wrong."
Steve Cotterill, the assistant chief constable of Derbyshire Constabulary, said it had been "one of, if not the most upsetting cases any of us has ever investigated."
"Six young children lost their lives needlessly in a fire and all our efforts have been focused on getting justice for those children," he said.
The jury was not told that Philpott had a previous conviction for attempted murder for stabbing a former girlfriend and her mother when he was 21 or that he was on bail for road rage at the time of the fire.
The conviction of the couple was front-page news in Britain, with publications seeing all manner of social ills reflected in Philpott's mustachioed face.
To the liberal Guardian newspaper, he was "a control freak whose domestic violence went unchecked." For the conservative Daily Mail, he was "a vile product of welfare U.K." To the Daily Mirror tabloid he was simply "pure evil."
But their defense lawyers painted a different picture.
Anthony Orchard told the judge Wednesday that "despite Mr.Philpott's faults, he was a very good father and loved those children."
"Mairead Philpott was an extremely good mother to all 11 children," her lawyer, Shaun Smith, said. "No one, we respectfully submit, can dispute the grief that she feels."
Judge Kathryn Thirlwall said she wanted to "reflect further" and adjourned sentencing to Thursday.
