Prosecutor Simon Taylor said Mr Ingham felt “a searing pain” in his right shoulder and as he got up from the floor was stabbed twice again.
As blood poured down his body, McKenzie then called the emergency services and told the operator: “He should be ******* dead!”
When the police arrived, McKenzie was seen on the floor rolling a cigarette, saying: “I’m sorry John. You just wouldn’t listen,” it was claimed.
Mr Ingham told the jury: “I felt frightened. I thought I would bleed to death.
“I was terrified because I take blood-thinning medicine and I started to panic as the blood was running down my legs and onto my toes.”
When police officers arrived shortly after 1.45am they were told Mr Ingham had taken the weapon from McKenzie and thrown it from the room before begging her to call an ambulance.
He was taken to the William Harvey Hospital in Ashford with what were originally thought to be life-threatening injuries, although he did not need surgery and has since made a full recovery.
