A son claimed he stabbed his mother to death - knifing her 17 times - after she said a cup of tea he made her was "not milky enough".
Thomas Westwood, of Rosemary Close in Tile Hill, Coventry, was jailed for 16 years after killing 68-year-old Susan Westwood.
It happened after an argument erupted at the victim's address in Cavendish Road, Coventry , on Friday, December 1, 2018.
Unemployed Westwood was arrested at the scene and claimed the row broke out after he made a cup of tea for his mother which was "not milky enough".
The 46-year-old claimed his mother bullied him every day and was to blame for initiating the knife attack. He described her attacking him with the knife first.
A post-mortem examination found Susan Westwood died as a result of 17 stab wounds.
Westwood admitted manslaughter on the day his trial was due to begin last June.
On Tuesday, April 16, Westwood was jailed for 16 years for manslaughter on the grounds of diminished responsibility.
