A medical student wept in court as she was shown pictures of her former home and told how her doctor father had repeatedly slammed a door on her mother’s arm during a row at the mansion.

Marianne Inglis, 21, said the relationship between her mother Elizabeth, a nurse, and her father, Dr Fraser Inglis, was “like an illness”.

Dr Inglis, 51, the founder of the Glasgow Memory Clinic, denies assaulting his now-ex wife.

Ms Inglis, who is studying to be a doctor at the University of Dundee, told prosecutor Adrian Fraser: “I think they both loved each other but they can never be together because their morals and values completely conflict.”

She said during her teenage years her mother was an alcoholic and her “terrible” drinking led to violent arguments.

She recalled the incident with the door, which is alleged to have happened in February 2010 at the former family home in Glen Road, Dunblane.

She said: “I was 14 to 16. I was watching TV in the evening after school. Mum was in the kitchen. She was volatile.

“The tension built up because when she drank her mood started to change and I knew she was looking for a fight. She was saying horrible things to me, like ‘you’re evil, you’re a nasty person, you have no friends’.

“I was livid because it was just another night of arguing and chaos from her drinking.

“My father was quiet for a while, if I remember correctly, and then he started shouting for us to leave us alone.”

Ms Inglis told the court that her mother tried to come into the TV lounge, and her father had closed the “heavy, sharp-edged wooden double door” on her arm several times.

In a statement Ms Inglis gave police, which she confirmed as factually correct, she said: “My dad shut the door violently on my mum’s arm to stop her coming in the room.

“He started thumping the door on my mum’s arm in a blind rage.”

She said the next morning her mother’s face “came up all bruised”.

She added: “It was horrific.”

Her young brother and sister were both sleeping upstairs while the alleged incident occurred.

Earlier, Elizabeth Inglis, 45, told the trial, which began last September, that she had gone into the TV lounge to question why her daughter was not doing her homework.

She claimed Mr Inglis “flipped”, closed the door on her arm as hard as he could, wrestled her to the ground, and “very slowly and deliberately raised his foot and stamped not once but twice” on the side of her head.

Mr Inglis of Leny Feus, near Kilmahog, Perthshire, who carries out pioneering studies into Alzheimer’s disease, denies assaulting his ex-wife, who is also known as Elizabeth Rowbottom, and now lives in Doune.

John Scott, QC, defending, accused Mrs Inglis of making up the allegations and being prepared to blacken her ex-husband’s name.

Mrs Inglis said his accusation was “ludicrous”.

Ms Inglis told Stirling Sheriff Court that when she was a child, her mother was “out of control” and their relationship was “awful”.

She said she had not wanted to give evidence, and said during her childhood she had been “torn between her parents”.

She said: “I never knew who to believe because they argue black is white and white is black.”

She added that her mother was now “a changed woman”, sober for over three years.

Thanking her for her testimony, Sheriff William Wood told her: “I think we all know how difficult its been for you, caught between two parents, giving evidence.”

The Crown case has now closed. The trial will resume on July 11.
