A man who fatally stabbed his sister’s boyfriend following a Christmas Day row has been sentenced to eight years in prison.
Adam Jenkins was cleared of murder but found guilty of manslaughter by a jury at Newcastle Crown Court.
CCTV footage captured the moment 39-year-old Birch sustained a single, fatal wound outside Jenkins’ home.
Paramedics tried to save him but he died shortly after.
Jenkins, 36, of Sunderland Road, Newbottle, was arrested at the scene.
The party on Christmas Day had started in high spirits.
However, late into the evening, eye-witnesses reported Birch attacking his own partner, the sister of Adam Jenkins.
Jenkins had been asleep but was woken by the disturbance. A confrontation between the men ensued.

They were separated, with Jenkins being ushered into the kitchen and Birch outside.
Jenkins then took three knives and went onto the driveway where the fatal incident occurred.
He maintained that he had never intended to harm his former friend.
He said, due to the stress and anxiety of the situation, he had no memory of taking a weapon or inflicting the wound.
Summing up, the judge described Mr Birch as a young man who “had much of his life before him and would have turned 40 this year.”
She added he was much loved by his family and, although he was described in court as a violent man, he did not have the chance to answer back or explain himself.
"I am sure," the judge continued, "you did not form the intent to cause Simon Birch serious harm or death."
After the attack Jenkins was reported as helping at the scene as best he could.
He was sentenced to eight years in prison with release from custody after serving two thirds of his sentence- serving the rest in community service.
