MI5 spy 'unhappy with ex's calls'

An MI5 spy accused of assaulting his fellow spy ex-girlfriend went to another phone to call her at work when she ignored him, a jury has heard.

The woman, referred to by her MI5 "pin number" 2363, then answered the call but became "uncomfortable", Southwark Crown Court heard.

The defendant, using false name Mark Barton for security reasons, denies two assault counts and one of harassment.

A sexual assault charge was dropped during the trial.

Flat visit

A former line manager of the woman told the court that, a few weeks before the woman complained to police about Mr Barton's behaviour at the end of August 2011, he was "aware of an occasion when 2363 took a telephone call that she was uncomfortable with taking".

"At the end of the call, she told me it was the defendant," the line manager said.

"She said there had been other attempted calls that she didn't take when she realised what number it was coming from, but the one she took came from another internal number - she assumed that he had gone to another phone to call her."

The court heard that 2363 ended the couple's year-long relationship in July 2011 but that they slept with each other on 11 August when she went around to his flat to collect clothes.

She said she had insisted the next morning she did not want a relationship with Mr Barton.

He harassed her and repeatedly sent her emails and text message begging to be part of her life, she claims.

The trial, which started on Monday, is being held under tight security to protect both their identities.

'Bear hug'

Earlier this week, the court heard that Mr Barton was "out of control" after 2363 left him.

She said that, after following her from a work party, Mr Barton had lifted her off the Tube in a "bear hug" and forced her to return to his flat.

Mr Barton had wanted to discuss their relationship and did not accept the romance was over, she said.

The woman said she had tried to leave but Mr Barton physically restrained her, throwing her into a cupboard.

The trial continues on Monday.
