Murderer Anthony Porter has been jailed for 19 years after a jury found him guilty of repeatedly raping and assaulting a woman.

The 33-year-old targeted his vulnerable victim and showed no remorse for what he had done, a judge told him.

As he is currently serving life, with a tariff of more than 17 years, for killing Andraya Lyons in December 2016 the new sentence is only likely to affect his getting parole.

But should the killer, who remained emotionless in the dock as he was convicted and sentence, ever be freed he will have to register as a sex offender for the rest of his life.

Porter had pleaded not guilty to three counts of rape, one of which is a multi incident count alleging it happened on at least two occasions, and actual bodily harm.

But a jury of eight men and four women convicted him of all of the offences, which took place before March 24, 2014, following a trial at Swindon Crown Court.

Richard Williams, defending, said despite denying the offences his client had said he was sorry for some of his behaviour towards his victim.

He said that a psychiatric report prepared for the murder case showed he had mental health issues.

"One of his difficulties is alcohol. He has indicated to me this morning that that is something he wishes to address when he is ultimately released in to the community," he said.

"He will try and address that with the various courses offered in the prisons where he will be held."

Mr Williams said it will take his client a long time to come to terms with the impact of his offending and because of his position 'has not been able to offer full remorse'.

He said "He does accept he drunk to excess, he does accept he had been violent to her. For that he apologises."

Passing sentence Judge Tim Mousley QC said "Despite what Mr Williams has urged upon me I am satisfied that you showed no remorse for what you did.

"Once you pleaded guilty to murder and were arrested for these offences, that was the time to come clean and to admit it.

"For you it was the cowardly and arrogant approach to try and persuade a jury that she was a liar.

"You also claimed that you were truly remorseful for what you did to Andraya: that in my judgement would be more persuasive if you had come clean about what you did to this victim."

He said that the sentence for these maters should be brought to the attention of the parole board 'when or if you should be deemed safe for release'.

During the trial the jury heard Porter, who was a bully at school, had known the victim as they hung around together as teenagers.

But he repeatedly raped her, on one occasion putting a dumbbell weight on her neck causing her to pass out, when he forced himself on her as she visited his flat.

The heavy drinking scaffolder was also violent towards her, once stubbing a cigarette out of her chin when she asked him not to smoke close to her.

Porter denied the assault took place and said that while they had sex in the past it was always consensual.
