A father who had at least six children with his own daughter has been given a 40-year extended life sentence.

The man, who cannot be named to protect the identity of his victims, repeatedly forced two of his daughters to have sex with him over 20 years, and even raped one of the children he fathered with her.

On Friday, a judge at Swansea Crown Court labelled the man "wicked" as he was sentenced to 33 years in jail and given a further seven years to be served on extended licence.

He will have to serve at least 22 years behind bars before he can be considered for parole.

Judge Paul Thomas said: "What you did to your family over a period of around 20 years plumbed the depths of depravity.

"Your behaviour was utterly wicked."

During his trial the court heard the father posed as a mystic and sent instructions to his daughters through what they believed was a psychic phone app, instructing them to have sex with him and other men.

DNA tests later showed that six children born to one of the daughters had been fathered by him.

The man, from West Wales, was found guilty of 36 counts of rape and one count of assault by penetration following trial.

Following his conviction, Hayley Fackrell, of the CPS, said: "These sickening acts of abuse were carried out by a person that was supposed to protect and care for the victims, but instead he systematically controlled their lives, grooming them for his sexual gratification."

NSPCC Wales praised the bravery of the man's daughters in coming forward to report abuse suffered at the hands of their father.

A spokesman said: "This was a horrific series of sustained sexual offences carried out by a vile and reprehensible individual.

"The severity of the sentence shows the danger this person poses and his victims must be praised for their bravery in speaking out. This case shows how survivors of abuse can come forward and see justice served no matter how much time has elapsed."
