A jilted boyfriend who stabbed a married nurse to death in the street after she dumped him for her boss has been sentenced to life imprisonment.
Dariusz Miakienko, 47, followed Naudel Turner from the doctor's surgery and murdered her at a bus stop in Tottenham.
Miakienko, who had a wife and two children in Poland, then placed a kitchen knife on the mother-of-two's body and calmly rolled a cigarette.
He had begun a two year affair with Mrs Turner, 42, after she treated him at the Castle View Surgery in Tottenham.
But they broke up last year when Mrs Turner, who lived with her husband William, began a new relationship with Kevin McDonald, her practice manager.
Jurors unanimously found Miakienko guilty of murder today. Judge Aidan Marron QC sentenced Miakienko to life imprisonment with a minimum of 20 years behind bars for the “grotesque” killing.
The judge told him: “'You stabbed Naudel Turner to death.
“It is my clear perception she had decided at last to end her relationship with you in favour of being with another man and made her wish entirely clear to you.
“You stabbed her repeatedly and repeatedly in the face, in the neck and in the chest at lunchtime on a London street in front of many horrified observers.
"In my judgement this was a simple act of revenge which you had planned would occur in the event of your rejection,” he added.
During the trial Mr McDonald said he had been in love with Mrs Turner since he started seeing her in December 2010.
He said Mrs Turner treated Miakienko for a leg ulcer and he did not realise they had had previously had a relationship.
Mr McDonald said: “I told her he was a fantasist and possibly dangerous.
“I asked him (Miakienko) to stop stalking Naudel and hanging around the surgery. He said he was a free person and could walk wherever he liked.”
In the weeks leading up to her death Miakienko sent 1,000 texts to Mrs Turner and told her: “You are killing me slowly.”
Naudel was stabbed in the neck in Bruce Grove in what prosecutor Peter Finnigan QC described as a “remorseless and prolonged” attack in March.
Miakienko stayed near the body and appeared calm as he placed a knife on the woman and rolled a cigarette.
Members of the public tried to detain the killer and he was arrested near the scene.
