John Miller, 38, used an axe and knives to carry out the frenzied attack in their family home.
After carrying out the killings, Miller told police and psychiatrists that he believed he was being brainwashed by his computer.
He also claimed he believed a nuclear war was about to start, he could see aliens from his back garden and he had made a tin foil hat for himself to block out their signals.
Miller was sentenced to 15 years today after pleading guilty to manslaughter on the grounds of diminished responsibility over the killing of partner Sarah Laycock and daughter Abigail Miller at their home in Garforth, Leeds, on January 14 last year.
It can also be revealed today that Miller, a member of the far-right British National Party, decided to spare his other daughter Amelia on the grounds that she was “a pure Aryan”. She would later be found cowering upstairs by police.
Amelia was left for at least 12 hours in the house with the bodies of her mother and sister. The court heard that the youngster has been left so terrified of her father she now asks relatives “what is the size of the padlock on daddy’s door?”
The court heard that Miller told police he carried out the killings on January 14 last year, stabbing his partner 19 times around the face, neck and chest - with one wound going through her eye.
He then hit her four times in the face with an axe.
The court heard that Abigail must have put up a considerable struggle, due to defensive injuries she suffered.
She was finally killed with a wound to the neck.
Police found Miss Laycock’s body in the kitchen and her daughter was in the living room.
The court heard that police officers who were called to the incident and who were involved in the investigation were deeply affected by what they witnessed. One officer has since resigned due to the trauma.
After leaving the house, Miller went on a violent rampage, attacking paramedics who were called to the Fairburn Ings nature reserve.
When they fled, leaving him in the ambulance, he took off his clothes and was shouting and making racist remarks when officers arrived.
Miller told police that the night before the killings, he ate with his family and said it felt like their last meal together.
He also said they watched Coronation Street together.
The judge said Miller had a “jealous and controlling” nature and was clearly a dangerous man.
He said three psychiatrists disagreed about whether Miller was a paranoid schizophrenic and should be treated in a mental hospital.
The judge said he had decided it was not appropriate to grant a hospital order in this case.
