An Old Bailey jury has gone out to consider whether Vikramgit Singh is guilty of murdering Battersea call girl, Gemma Dorman.

Earlier in the trial, they heard how Mr Singh, 25, plunged a seven-inch carving knife into his ex-girlfriend's stomach in Lavender Hill, Battersea, on July 31, 2008.

Before the killing, Singh, of Ruskin Road in Southall, bombarded her with up to 30 text messages a day and sent love letters begging for her to return his affection, it was alleged.

The court heard how Miss Dorman, from Wandsworth, met Mr Singh while working for Vixens Escort Agency between July 2005 and June 2007.

The pair began a relationship, but Miss Dorman broke it off several months after she left the agency, saying she never wanted to see him again.

Mr Singh, who earned just £400 a week, later claimed he had given her about £260,000 to make her stay with him.

After a barrage of love letters and text messages, Miss Dorman and her mother reported him to the police for harassment.

Miss Dorman was in the Amazing Thai restaurant with her new fiance the night she was killed.

The jury has been told to consider whether Mr Singh should be convicted based on his intent, diminished responsibility or provocation. He denies murder.
