Porter, 32,  allegedly, murdered his estranged girlfriend by beating her with an iron, pouring paint down her throat and setting her house on fire after they argued at a Christmas party, a court has heard.
Anthony Porter broke into the home of mum-of-two Andraya Lyons, 38, after she told him their relationship was over and left the party without him.

Andraya Lyons, broke up with Porter on the evening he killed her

Bristol Crown Court heard Porter attacked Lyons viciously after entering her house in Swindon, Wiltshire, in the early hours of December 10 last year.
Porter punched, kicked and stamped on Ms Lyons as well as hitting her with an iron, causing 45 separate injuries in the brutal attack.
He poured grey paint down her throat while she was unconscious then set her home on fire while she was still alive.
Emergency workers discovered the body of Ms Lyons, who had sons aged seven and five, in her lounge after neighbours reported the smell of smoke.
Porter handed himself in to police hours later and admitted the savage killing, which he described as “five minutes of madness”.
Judge Peter Blair QC jailed Porter for life and ordered him to serve a minimum of 17 years. He told Porter: “This was a sustained assault beginning from the moment you broke into her home, with her shouting for you to get out.
“It is clear that you inflicted suffering to her both mentally and physically before subduing her until she fell into a state of unconsciousness.
“What you then did to her unconscious body was appalling.”
Prosecuting, Colin Meeke said the couple had been together since summer 2015.

They attended her work Christmas party, at the Marriott hotel in Swindon, on December 9 and Porter drank heavily.
Mr Meeke said Porter was known to become violent after drinking, with pals later telling cops he could “change after just one drink”.
The court heard he became “loud, drunk, lewd and aggressive” at the party and at one stage tussled with a visibly distressed Ms Lyons on the floor.
Mr Meeke said: “He was pulled away from her, swearing aggressively and she told him that it was all over.”
Friends ordered Ms Lyons a taxi and as it drove away, Porter punched the window and said: “I’ll break into the house and torch it.”
Ms Lyons arrived home at about 1.20am and neighbours heard shouting at about 2am, when Porter entered the property.
Neighbours described hearing about 15 “thudding sounds” and a woman screaming for up to six minutes, Mr Meeke said.
At 5.37am, Porter texted a friend: “Some of us have angels, some of us have demons. Tonight the demons won.”
EMTs discovered Ms Lyons’ body after arriving at the burning house at 5.57am.
A post-mortem found the mum died from a combination of the fire, inhaling the paint and head injuries causing by Porter.
Mr Meeke said: “She had been breathing, quite probably unconscious, when the fire started and she had been breathing when the paint was poured down her throat.”
Her 45 injuries included a broken nose, bruising and cuts to her face and defence injuries on her arms.
While being quizzed by cops, Porter – who has previous convictions for violence – said he could not explain his actions.
Robert Ross, representing Porter, apologised to Ms Lyons’ family and read a letter written by his client.
The letter read: “Even when I get released I am going to go to sleep thinking about what I have done – the guilt that I have taken the boys’ mother from them, it eats me up every time I think about them.”
In a statement released through Wiltshire Police, Ms Lyons’ family paid tribute to her as “a generous, fun-loving, bubbly, caring person” and urged those experiencing domestic abuse to seek help.
