GWENT businessman Peter Morgan admitted to police that he had killed his lover Georgina Symonds - but said he did not know why he had done it.
The jury at Morgan's trial on the charge of murder was shown footage of a police interview from January 13 this year, the day after the killing.
In reply to the question: "Are you responsible for the murder of Georgina Symonds?" Morgan tells Detective Constable Virginia Davies "yes."

He now denies murder on the grounds of diminished responsibility.

In the interview he goes on to tell DC Davies: "I don't know why I did it. I loved her. I gave up everything for her."
He said the problems began in mid-November last year, after Miss Symonds' former lover killed himself.
"She was very angry and emotional about it. At times she blamed me for it," said Morgan.
"She was looking for people to blame and I was the easy person to blame."
"The longer it went on, the more she would blame, the more angry she would get."
He said Miss Symonds did not seek any help, but would drink and take cocaine.
"When I came down she would be a very angry person and difficult to reason with.
"I found it very difficult to try to stand up to her.
"She would not go to the doctor's. She was just at home in a state.
"Once she told me it was my fault (about social services being called in) I just lost it.
"I didn't want to be the reason she lost her daughter. It was bad enough to be blamed for the loss of her partner.
"I don't know why but I thought, if I can't sort it out I am going to kill her.
"Honestly, I don't know what made me do it." 
Morgan described collecting items such as plastic sheeting and baling twine before going to see Miss Symonds at Pencoed Castle Bungalow, a property of his where she lived, near Llanmartin, on the morning of January 12.
"I wanted her to stop blaming me. I was quite happy for her to have as long as it took to grieve, but I could not stand her blaming me and wishing I was dead, and hating me.
"I just wanted her to stop doing that.
"I don't know what I was planning. I thought I would frighten her.
"I sort of said to her, we have got to sort out where we are going.
"She got to blaming me again and saying it was all my fault.
"I just put the cord around her neck and strangled her.
"I didn't think I could do it.
"I planned it, well, I don't know if I planned it. I had thought about it the night before."
Morgan told DC Davies he had felt no remorse.
"I don't know what I felt," he said.
"I don't think I have got mental problems but she was my life.
"I just held the thing until she stopped breathing."
He said he put the body, wrapped in plastic sheeting, in the boot of his Porsche 4x4 before two of his employees arrived with a bath for the bungalow and after helping them unload it, he went to Beech Hill Farm in Usk and hid the body in a workshop then went about his normal business.
"I didn't feel any guilt. I don't know why. I loved her," he said.
Attempting to describe it, he suggested it might have been "a crime of love, a crime of passion."
Morgan described in his police interview how he had the baling twine in his pocket when he arrived at the bungalow.
He said Miss Symonds had warned him on the phone the previous day that she would be angry and she was.
She began blaming him again and he "just put the cord around her neck and strangled her."
He said they had been sitting on the sofa when he did it.
"It was the blaming I couldn't take," he said.
Morgan repeatedly stated throughout the interview that he could not believe he had killed Miss Symonds, at one point asking himself "why, why?"
He said he was calm during the hours leading up to the killing and even when he went into the bungalow he remained so.
He also said that at that point he still did not know that he was going to go through with it.
He described how he had "lurched across" the sofa they were sitting on and looped the twine around Miss Symonds' neck.
Afterwards, he said he thought he had checked her pulse but could not be sure.
He said he had then wrapped her body in sheeting but had not thought about where he was going to take it.

He took it to Beech Hill Farm in Usk and hid it in his workshop.

He said he was still feeling calm, and added: "I have not cried at all. I just cannot believe it. I still love her, I still want her.

"Why haven't I got any emotions towards her? I cannot believe I have done it, still. Why did I do it?"

He then described going to the bungalow after being told Miss Symonds had not picked up her daughter from school, and told of how the police were called and his stories unravelled.

By the time he was taken to Maindee police station late on January 12, after Miss Symonds' phone had been recovered from his Porsche sports car at Llanellen, Morgan had resolved to tell all.

"As I was now there, I thought I'll just tell the truth," Morgan told DC Davies.

He told thought about telling the police earlier, at the bungalow, but did not want to do it in front of Miss Symonds' friends and family. 

Previously, the court was told that earlier in the evening, after Miss Symonds had been reported missing, Morgan told police at the bungalow that she may have gone to confront his wife in Usk, after a police trace confirmed that it was last contacted in that area.

Morgan then told police he had taken her mobile phone from her to stop her buying drugs - despite seemingly having attempted to contact her mobile phone in an effort to find her earlier, after her family and friends became worried.

A video was played to the jury showing Morgan - recorded on a police officer's bodycam at Pencoed Castle Bungalow on the evening of January 12 - attempting to explain this anomaly to another officer.
