Woman in fatal love triangle says: 'If I had never brought him to my house he would still be alive'

The former girlfriend of a man who stabbed her lover after coming home while they were together has begun giving evidence at his murder trial.

The woman in a "love triangle" that allegedly resulted in a man being stabbed to death has told a murder trial: "It is my fault. If I had never brought him to my house he would be still alive. I'm so sorry."

Claire McGrath also told the trial that the deceased "burst in" to the room where she was arguing with the accused and said "she's mine now" before the fatal row broke out.
