Peter Madsen, Danish Innovator has been sentenced to life imprisonment without parole for the murder of the Swedish journalist Kim Wall on his submarine.

Madsen had planned to kill Ms Wall, 30, either by suffocating her or cutting her throat, the Copenhagen court heard.

Her dismembered remains were found by Danish police at sea on 21 August last year, 11 days after she interviewed him on board his homemade vessel.

Madsen, 47, has said he will appeal against the conviction.

He was found guilty of premeditated murder and sexual assault after previously admitting to dismembering Ms Wall's body on the submarine and throwing her remains overboard.

His claim that Ms Wall's death was accidental was dismissed by the court.

The case was heard by Copenhagen City Court Judge Anette Burkoe and two jurors.
