Muhammad Javed, 59, of Staines Road, Ilford, was convicted at the Old Bailey on Thursday, 30 May after a ten-day-trial.
The court heard how on Tuesday, 13 February 2018 he had brutally attacked his wife Saeeda Hussain, 54, with a meat cleaver and then gone to a police station to confess his crime.
The pair had been married for 18 years, but Javed had a controlling personality and other family members told police he could become angry at the slightest thing.
So bad was his controlling nature that he had installed CCTV cameras in the house, so he could monitor Saeeda in case she was cheating on him.
The family also told police that Javed had abused and assaulted Saeeda many times over the years, but none of this was ever reported to the police and the abuse continued unabated.
In the weeks leading up to the murder he had apparently been getting angrier and angrier with his wife and other family members, and they had begun to fear for their safety.
Police were alerted to the murder when Javed entered Ilford police station and told officers he had killed his wife.
Javed had also phoned other family members and told them what he had done and they had made their way to the house.
As they entered, officers also arrived and asked the family to wait outside.
The officers found the door to the downstairs living room had been locked and they forced entry.
They found Saeeda lying on the floor and it was apparent she had been brutally assaulted – attending paramedics pronounced her dead at the scene.
Saeeda had multiple wounds to her head and arms and beside her body were a hammer and a bloody meat cleaver. Also in the room was a discarded blood covered boiler suit that Javed had apparently worn during the attack.
A subsequent post-mortem examination on 19 February 2018 gave the cause of death as multiple injuries and indicated Saeeda had been subjected to a sustained and brutal attack.
He will be sentenced on Tuesday, 21 June.
Detective Inspector John Marriott of the Homicide and Major Crime Command, said: “The only person who ever thought Saeeda was cheating was Javed, and this was the product of his own warped mind.
“I have no doubt that Javed planned this assault to coincide with a time when he knew his family were away from the home. He probably donned the boiler suit, which we found blood-spattered, to avoid getting his wife’s blood on his clothes.
“Javed was controlling and violent and this escalated in the brutal murder of his wife, Saeeda. If ever a case shows the importance of contacting police if you are in, or aware of, an abusive relationship, then this is it.”
