A High Wycombe businessman who literally kicked a woman out of bed and left her with a broken wrist after a row over sex has been found guilty of causing grievous bodily harm.

The married international education entrepreneur was convicted by a jury at Isleworth Crown Court of the charge after the Russian intern he was having a relationship with broke her wrist as she fell against a wall.

Cambridge University-educated John Crawford Florey, 48, of Chequers Avenue, High Wycombe, met the woman when she was seeking an internship with his company.

They had spent an evening at an education symposium at the London School of Economics and returned to an apartment Florey had rented for the night in Royal Crescent, Notting Hill.

However, the court was told that Florey flew into a rage when the woman refused to undress and kicked her out of bed.

Prosecutor Neil Griffin said: "It was a kick of such force that she fell against the wall and fractured her wrist.

"They had attended a function in central London, went out to eat and went back to the apartment.

"It seems the defendant rubbed toothpaste into her dress as they were brushing their teeth in the bathroom and this upset her along with him going out to smoke because she did not like smoking.

"She decided to keep her dress on and the defendant had undressed down to his boxer's and tried very roughly to kiss her.

"He had a second cigarette and returned to the bedroom and forced himself onto her and she told him he was hurting her.

"Suddenly he kicked her, she says, to the back. She fell out of the bed against the wall and onto the floor and Mr Florey shouted: 'Get out.'

"She grabbed her clothes and left in hurry, flagged down a taxi and was taken to St. Mary's Hospital, where her wrist was put in a cast."

The woman reported Florey to police the next day and he was arrested at Heathrow Airport returning from a foreign business trip.

He was questioned at Notting Hill Police Station and gave a conflicting version of events.

The prosecutor told the jury : "He said he thought they were going to have sex and thought it was strange she left her dress on. He said he made the remark that she was not great in bed and she went mad and stumbled and fell over while they were arguing."

The woman told the jury she knew Florey was married, and that she had often met up with him in central London and sometimes using a flat in Shepherd's Bush.

She said they began a sexual relationship in July, 2013, but she said she soon tired of his aggressive behaviour and they had a short break-up before getting back together.

"Whenever I was late he was so rude, he was quite sadistic I would say and I could see he became violent," she said adding that their sex life was often a cause of arguments.

"When I didn't do it the way he wanted he got pretty aggressive."

She went on to say that Florey could be "quite violent" and "unpleasant" toward her.

Mr Florey's sentencing has been adjourned until February 27.
