A father convicted of starting a house fire that killed six of his children in Derby has been jailed for life at Nottingham Crown Court.
Mick Philpott was told he would serve a minimum of 15 years in prison.
His wife Mairead Philpott and friend Paul Mosley were sentenced to 17 years in prison and told they would serve at least half of that.
The trio were found guilty of manslaughter yesterday after a trial at Nottingham Crown Court.
As she sentenced them today, Mrs Justice Thirlwall said: "I have not the slightest doubt that you, Michael Philpott, were the driving force behind this shockingly dangerous enterprise."
Justice Thirwall described Mr Philpott as a "disturbingly dangerous man" with "no moral compass", and said his guiding principle was "what Mick Philpott wants, Mick Philpott gets."
Mr Philpott, 56, his 32-year-old wife and Mosley, 46, were all found guilty of killing Jade Philpott, 10, and her brothers John, nine, Jack, eight, Jesse, six, Jayden, five, and Duwayne, 13, in the fire at their home in Victory Road, Allenton, Derby, in the early hours of May 11 last year.
The three started the fire in an attempt to frame Philpott's ex, 29-year-old Lisa Willis, after she left the family home with her children three months earlier.
Justice Thirwall told the three defendants that there was "no precedent" for the case, and added: "It is, in my judgment, a uniquely grave set of offences."
Mr Philpott looked down at the floor, wiping tears from his eyes, as the judge passed sentence.
Mairead Philpott wept as she was jailed. Mosley showed no reaction, sitting motionless and looking over at public gallery.
Family members in the public gallery applauded as the judge finished her sentencing.
One shouted: "Die, Mick, die."
Another said: "See you, Mairead. Hope you enjoy life on your own."
"Your own babies," another called out.
In response, Philpott smiled and made an obscene gesture as he was led from the dock.
The judge said that Mick Philpott had become obsessed with his ex 29-year-old Lisa Willis, after she left the family home with her children three months earlier, and had done everything to get her back.
Justice Thirwall told Mr Philpott: "You could not stand the fact that she had crossed you. You were determined to make sure she came back and you began to put together your plan."
