Alicia confided in her GP on July 23 last year and Mitchinson was arrested and questioned. “He said she was intoxicated during the theatre outing and she threw the glass at him and he had to restrain her.”Miss Paul told the jury: “He sought to control her whole life, her work, her sleep pattern her social life. She was, in effect, her husband’s prisoner.”Mitchinson, of Holmdale Road, West Hampstead has pleaded not guilty to one count of controlling or coercive behaviour between January 1 and July 23 2016.He also denies three counts of assaulting Ms Vidler at their home address on dates between January 10 and July 16 2016.He said the demise of Castilium prompted Alicia’s police complaint, which is “fabricated and exaggerated.”The trial continues. She told the trial: “He’d tell me before business meetings: ‘You’re going to have to get through this. You’re probably going to be crippled for life so you have to make this work.'”Guy did not like me being seen with crutches or a walking stick and I’d leave them at reception. Flying makes it much worse, it’s very painful on the plane.”The couple married in July, 2014, but Alicia said there were problems from the start.”He hated me seeing my friends,” she said, “he started asking for the passwords to every electronic device I had.””It terrified me, it gave me no privacy. I felt I was being monitored, my personal thoughts are on them, my bank account details.”I couldn’t get away from him, I couldn’t think straight. It scared me in the end and made me feel incredibly stressed.” Guy MitchinsonCredit:Tony Palmer Caroline Paul, prosecuting, told the jury: “This trial is about a man systematically bullying his wife in order to control her and he became more controlling and violent between January and July, last year.”His wife became his virtual prisoner and he began to interfere with her medical care, forcing her into taking a course of medication when the the side effects were severe.”Ms Vidler was an equity derivatives trader with Deutsche Bank in Sydney before moving to the UK, where she studied for a PhD in mathematics at Imperial College.She was privately-educated at Sydney’s Ascham school and co-founded Mayfair’s Castilium Capital with her husband in January 2012.Mitchinson claims her allegations are invented and simply a way of getting out of the marriage and failing business partnership.However, recalling one row, Ms Vidler told he court: “He smashed a glass on my head and it smashed everywhere, it was the crown of my head and there was glass in my hair and I could feel blood on my head.”I made a run for it and got the front door open and saw the beautiful blue sky and houses, but he got me by the hand and swung me back into the house.”I spent the next five hours trying to get past him, that’s what I was fixated on,” she added. “He said: ‘I’ll not let you do this to our marriage.'”He said: ‘No one is coming to rescue you.’ I begged twenty or thirty times to go to hospital and thought about climbing out the bathroom window, but there is an eighteen foot drop.” A hedge fund boss told his disabled wife to leave her crutches behind to stop them losing clients, a court heard has heard, as he is accused of systematic abuse.Former Deutsche Bank derivatives expert Guy Mitchinson, 38, ran Castilium Capital with wife Alicia Vidler, an ex-Merrill Lynch trader, who says she was a prisoner of her violent husband.The 37-year-old claimed her husband, who denies “systematically bullying” his wife at their Knightsbridge home, smashed a glass over her head during a row.The hedge fund manager ignored his wife’s painful arthritic condition as she rested at their £3.4m home, beating her with a pillow as she rolled herself into a ball, Isleworth Crown Court heard.
