A man was jailed for life today for killing his mother because she would not move out of the family home.
Nasir Uddin, 32, stabbed frail Khyrun Nessa, 70, five times with a knife and left her in the hallway for other members of the family to find, the Old Bailey heard.
Uddin had been had been distressed because Mrs Nessa had refused to abandon her home in Byng Street, Isle of Dogs, east London.
Uddin was found guilty of murder following a retrial and told he must serve at least 22 years.
Judge Giles Forrester told him he had committed a "wicked and cruel" crime.
The judge added: "This was a horrific attack giving rise to a brutal and shocking murder.
"You were her youngest son. I cannot imagine a greater breach of trust than a son who murders his mother."
Judge Forrester said he accepted that Uddin had been left in the middle because his wife Daisy and mother did not get on.
But he told the father-of-two that many other people in the same circumstances make the best of their lives.
Jeremy Donne QC, prosecuting, told the trial: "He and his mother had been joint tenants of that house.
"They had been living there together until a few days before August 12 last year.
"For some time, he had been trying to persuade her to leave the house and live with another family member, or to leave the house and go to Bangladesh so he, his wife and children could have the house."
But Mrs Nessa, who was "vulnerable and frail" and was recovering from an operation for cancer, wanted to stay because the house had been adapted for her disability, said Mr Donne.
He said that Uddin, who had moved out a few days before, turned up "during a 55-minute window of opportunity" to try again to persuade her with £1,000.
"In a vicious tempter and frustration, he took out a knife and killed her," added Mr Donne.
Uddin, of Finsbury Park, north London, denied the murder in August last year.
Oliver Blunt QC, defending, said: "Something must have happened to turn a law-abiding, decent man into a killer."
