Justin Lee Collins has been found guilty of harassing his former partner.

A jury at St Albans Crown Court heard that the 38-year-old TV presenter subjected video games public relations worker Anna Larke to sustained emotional and domestic abuse during their seven-month relationship, and made her write down in a Pukka pad all her previous sexual encounters regardless of how graphic.

The court was told that Collins made her sleep facing him, throw away DVDs because they featured actors she found attractive and made death threats against her.

Collins did not show any emotion as the verdict was announced.

During the trial, the jury heard that Collins, who made a name for himself as a host on Channel 4’s The Friday Night Project, was a controlling, jealous boyfriend who assaulted Ms Larke.

The court was told he made her write down every sexual encounter she had ever had and stopped her using social networking sites such as Facebook and Twitter after reading her messages.

Jurors were played a secret recording she made of him verbally abusing her during a row, in which he called her a “f****** slag”, a “dirty vile whore”, and a “f****** sex addict”.

He said the recording showed him at his worst but denied all her other claims. He told the court he had never attacked her in any way and had never hit anyone in his life.

Collins said he had only ever slapped Ms Larke to calm her down when she was self-harming, which he claimed she did, once gouging her wrists and threatening to kill herself.

Ms Larke claimed Collins attacked her in a hotel room in Miami in March last year. Giving evidence to the court, Ms Larke said she had not shown her doctor her bruises because she did not want to get Collins into trouble.
