A “controlling” High Wycombe businessman has been jailed for 18 months after he kicked his mistress out of bed – breaking her wrist in the process – when she spurned his advances.

Married businessman John Crawford Florey, 48, had attended an education symposium at the London School of Economics with 40-year-old Russian intern Olga Grigorash earlier in the evening and enjoyed some drink at dinner.

Florey, of Chequers Avenue, then took his companion back to the flat he had rented for the night.

Isleworth Crown Court heard she refused to undress for him and lay fully clothed on top of the bed.

The prosecution told jurors Florey lost his temper after he forced himself onto her and she complained he was hurting her. At this point the court heard he kicked her off the bed, causing her to fall against a wall and break her wrist.

Sentencing the Cambridge-educated Florey, Recorder Philip Shepherd QC told him: “I take into account the humiliating remarks you made to Ms Grigorash before the assault. You were trying to force yourself sexually on her and she was unwilling to have sex with you, which should have been apparent.

“You used considerable force to kick her out of bed when your advances were rejected and the injury is one she still suffers continuing effects.”

Florey was convicted by a jury at an earlier hearing of inflicting grievous bodily harm on Ms Grigorash at the flat in Royal Crescent, Notting Hill in the early hours of March 4, last year.

The judge noted that Miss Grigorash said Florey made no attempt to help her and she made her way to hospital alone, where her wrist was put in a cast.

She reported Florey to police the next day. He was arrested at Heathrow Airport returning from a foreign business trip, then questioned at Notting Hill Police Station and gave a conflicting version of events.

The prosecutor said: “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.”

Miss Grigorash told the jury she knew Florey was married, and often met up with him in central London and sometimes they had used a flat in Shepherd's Bush, where his parents and sister lived.

She had told the jury that they had begun a sexual relationship in July, 2013, but she said she had soon tired of his aggressive behaviour.

Florey’s counsel, Stuart Stevens told the court : “He was a respected gentleman. He did have good character and he's lost that.

“He feels totally disgraced and ashamed and the hardest thing was telling his mother.

“This was out of character and was not calculated. It was an over-reaction, he says, to being told he was not rich enough.

“He earns a decent living, but is not a rich man and with this conviction he will not be able to go to certain countries now.

“He spends much of his time abroad and makes a successful living and is highly-regarded by universities and the Chamber of Commerce.”

Mr Stevens added : “There was a lurid report of the case in the Bucks Free Press newspaper, it is salacious, a Sun-type report. All his neighbours know about it, it is all over the area.”

Recorder Shepherd told Florey he was unable to treat him as a man of good character because he was cautioned in 2011 for punching a former pupil at a school reunion when an old playground rivalry resumed.

“She still suffers anxiety and panic attacks and can't lift objects with her right arm or play sports, particularly tennis for which she has a particular love and is unable to drive a car.

“You were in drink that night, which I consider an aggravating factor and your behaviour was controlling and overbearing towards her in the previous year.”

Florey was also made subject to an indefinite restraining order, prohibiting him having any contact with Ms Grigorash and he was ordered to pay her £6,000 compensation and £2,800 court costs.
