Emma Greville described how she put her arms around his waist and pulled as her sister pushed with her legs and said, that as she did so, he “turned to the right and his elbow touched my jaw”.

“As a result, I let go,” she said.

She said he did not mention what had happened, “even though I was visibly upset” but he did say he was “disappointed” in her, she said.

Emma Greville said the argument between the couple continued and moved into the kitchen, where the alleged headbutt then took place.

‘Looks less staged’

The court also heard Emma Greville had been critical of a photograph her older sister arranged to be taken a couple of days after the alleged assault on 1 November that appeared to show her injuries.

Kate Greville previously told the court the photo was taken in an attempt to get the paparazzi off her back.

Asked about a series of messages between Kate Greville and her friend Courtney which showed the younger sister disagreed with the arrangement, Emma Greville confirmed to the court she thought it was immoral to set up a fake picture made to look genuine.

She was also asked about messages between the two sisters on 16 November, when the article was published.

In one, Emma Greville asked her sister how she felt about the article.

Kate Greville said in response, she thought she looked terrible, but that was probably a good thing as it “looks less staged”.

Emma Greville responded: “I think they are good photos as it looks real”.

Asked if the bruises were not real, Emma Greville told the court: “They were real.”

Emma Greville was asked if she had told the police her sister had staged fake photos. She said she hadn’t, but that her sister had.

The court also heard from Mr Giggs’ neighbour who said he was banging on her door after the alleged assault.

Linda Cheung, who had known the defendant for more than 20 years, said he was “distressed” and asked her to help him.

“He said words to affect that Kate had been accusing him of seeing other women and he wanted me to and sort her out,” she said.

Regarding the accusation of him seeing other girls, she said her reaction was: “Oh Ryan, not that again.”

He told her Ms Greville was refusing to leave. Mrs Cheung said she refused to go over as she did not want to get involved when she did not understand the situation. He later left.

Later, in the early hours. after she saw the police come and go, she said she saw a small white car arrive with two women and another male.

She described them “as screaming, shouting and laughing” and “running up and down the drive”

Kate Grenville had the dog Mack in her arms and was talking to him.

She described the mood as “high jinx”.

The court was also told a firm which employed Kate Greville had blocked Mr Giggs’ emails due to the quantity he was sending her.

Elsa Roodt said the email volume was “intense” and “Kate could not do her work”.

Ms Roodt, who has a public relations firm in the United Arab Emirates, was giving her evidence via a video link from Dubai.

She told the court Ms Greville had gone to help her and colleague Katie Harvey to set up a new office in Abu Dhabi in 2016.

She said Ms Greville was “happy and confident and bubbly” and had socialised when she first arrived.
