A man has been found guilty of raping a woman who fell asleep at a party in a "deliberate, degrading, disgusting attack".

Darren Anderson attacked the woman after she had kissed him during a game of "spin the bottle" at a house in Livingston, West Lothian.

The High Court in Edinburgh heard she woke after falling asleep fully clothed to find Anderson having sex with her.

She ran upstairs to where a friend had gone to bed and the police were called.

Anderson, 26, of Morrison Way, in Livingston, had denied raping the woman while she was asleep and incapable of giving or withholding consent on December 20, 2014, but was convicted by a jury at the court on Monday.

The 23-year-old woman told his trial: "I did not want to have sex with him at all."

She said she had been visiting a friend she had not seen for a while and they were planning to go out in Livingston but the other woman was not well.

Others arrived at the house, including Anderson, and a game of spin the bottle was played during which the woman, who was a victim liaison worker with a police force, kissed Anderson after she was dared too.

Anderson had asked her to go upstairs, saying it would "wind up" another of the men at the house.

The woman, who had had a few drinks, said she had kissed him again but when he made a further advance on her she told him to stop and he did.

She told the court: "I said 'I am not that type of girl' and he says 'I know you are not'. I can always remember him saying that."

Anderson had later gone to sleep on the couch after he asked if he could also sleep there.

She said there was "no kissing or anything" but she woke up to find him having sex with her.

Anderson later claimed to police during an interview that the woman had led him on all night.

He said: "She was over me all night."

He accepted he was touching her in an intimate way, trying to get her to wake up.

At one stage he told officers: "We didn't have sex. I guarantee."

He claimed he would be surprised if his DNA was found.

A swab taken from the woman confirmed he did have sex with her.

Advocate depute Mark McGuire told jurors: "He wanted sex. She was asleep. He did not care."

Mr McGuire said it had resulted in "a deliberate, degrading, disgusting attack on a helpless young woman."

The prosecutor accused him of being "a predatory man who took advantage of a woman" who had previously rebuffed him which he had accepted at the time.

Anderson had been on bail ahead of Monday's verdict but was remanded in custody after he was found guilty of the rape.

A judge deferred sentence on him for the preparation of a background report.

Lord Turnbull told him: "You have been convicted of a most serious offence."
