A Maoist cult leader who raped two of his followers and kept his daughter a "slave" for 30 years has been jailed for 23 years.
Aravindan Balakrishnan, 75, known as Comrade Bala, brainwashed his cult into thinking he had God-like powers and could read their minds, and subjected them to decades of abuse.
His daughter Katy Morgan-Davies, 33, formerly known in the press as Fran, has bravely waived her right to anonymity to speak out about the years of psychological and physical bullying she endured at her father's hands.
She told the Press Association: "It was horrible, so dehumanising and degrading. I felt like a caged bird with clipped wings."
Balakrishnan, of Enfield, north London, was impassive as he was sentenced at London's Southwark Crown Court.
He had been convicted of four counts of rape, six counts of indecent assault, two counts of ABH, cruelty to a child under 16, and false imprisonment.
The grey-haired pensioner idolised tyrants Chairman Mao, Joseph Stalin, Pol Pot and Saddam Hussein and wanted to be "bigger than all of them", his daughter said.
He ran his tiny south London cult, the Workers' Institute of Marxism-Leninism-Mao Zedong Thought, with an iron fist - banning his daughter from leaving the house or mixing with other children, and sexually assaulting two of his followers "by appointment".
Jailing him, Judge Deborah Taylor said: "You were ruthless in your exploitation of them.
"You engendered a climate of fear, jealousy and competition for your approval."
She added: "These are grave and serious crimes conducted over a long period of time and you have shown no remorse whatsoever."
He was assessed by a doctor and has a "narcissistic personality disorder" and has a "grandiose" sense of his own self importance, the court heard.
The judge said Balakrishnan had treated his daughter like "an experiment".
She said: "Your treatment of her from her birth to the age of 26 was a catalogue of mental and physical abuse.
"She was slapped with slippers or a stick from a McDonald's balloon you kept for the purpose."
To keep his devotees in check, Balakrishnan invented an invisible war machine called Jackie which he said could kill or trigger earthquakes if anyone went against his will.
In a bizarre and harrowing case, jurors heard how his daughter was effectively kept prisoner in the cult's house, and robbed of the chance to get to know her extended family or make friends.
She was the secret child of Balakrishnan and one of his followers Sian Davies, a former pupil at Cheltenham Ladies' College.
But growing up she was told she was a "waif" who had been adopted by the cult. Starved of affection, she was banned from leaving the house unaccompanied and routinely psychologically and physically abused.
As a child she became so lonely she would talk to the taps in the bathroom, and tried to make friends with the rats and mice that scuttled into the kitchen.
After 30 years being kept a "slave" she managed to escape the cult in 2013 after memorising the number for an anti-slavery charity she saw on the news.
She is now carving out a new - and finally free- life for herself in Leeds.
She said: "I've been a non-person all my life and now is my chance to be myself."
