A millionaire antiques dealer who strangled his seven-year-old daughter to death in an act of "pure selfishness" has been jailed for life.
"Deceitful and manipulative" father Robert Peters, 56, was sentenced to life with a minimum term of 24 years over the death of Sophia at the Old Bailey on Monday.
Peters throttled Sophia with a dressing gown cord while alone with her at his £1 million family home in Wimbledon, south-west London, last November.
Afterwards, he called 999 to report what he had done and the child was rushed to hospital, but died the following day.
The killing came just over a month after depressed and suicidal Peters was found not to be a risk by a child protection team.
But three days into his trial on Wednesday, he dramatically changed his plea.
Jailing him for life with a minimum term of 24 years, Mr Justice Edis said: "This was a determined pre-mediated killing in which there was an intention to kill.
"It is impossible to imagine the last few conscious minutes of that child's life. She was a lovely little girl who loved her parents and thought that they loved her.
"Asleep in bed, she no doubt felt safe and believed that should she need it she had the protection of her father.
"Her shock and bewilderment to find that he was set on her death amounted, in my judgement, to an intentional act of cruelty over an above the killing itself.
"I do not think the defendant intended to wake her up but when she did, he carried on anyway, now knowing that the death would not be a painless and oblivious event."
The judge said Peters was "deceitful and manipulative" and "calculating and disingenuous" in the way he hid his plans.
He added: "This was a premeditated crime carefully thought through and relentlessly executed."
