This morning, more psychiatric evidence will be heard in the murder trial of a Castletown man.
Ian Anderson, who's 46, denies the murder of 60-year-old Ballabeg man, Neil Roberts, in late 2013.
Yesterday forensic psychiatrist Dr Ramneesh Puri gave evidence for the defence and was cross-examined by the prosecution.
Dr Puri told the court Mr Anderson met the criteria of an 'Emotionally Unstable Personality Disorder.'
He said Mr Anderson exhibited variability of personality - he would jump from extreme emotions in a short amount of time.
Linda Watts, prosecuting, asked Dr Puri what the disorder meant on the night of the alleged murder.
Dr Puri said Mr Anderson would've had the disorder in its full form from his mid-twenties and it would've been a factor on the night of the incident.
Dr Puri said he thought he was suffering from "morbid jealousy" and on the night of the incident had finally heard his wife and Mr Roberts confess they were having an affair.
The trial continues tomorrow morning at Douglas Courthouse, from 10am.
