A Hampshire mum wept as she was told she would serve at least 11 years in jail for battering her mother in law to death.
Rajvinder Kaur used a wooden rolling pin to rain at least 20 blows to the head of 56-year-old Baljit Buttar before leaving her in blood-soaked bathroom.
At Winchester Crown Court Judge Mr Justice Burnett jailed Kaur for life to serve a minimum of 11 years behind bars.
He described the murder as “frenzied” after she “exploded with rage” because she was being nagged on the morning of February 25 2011.
Sentencing Kaur, 37, her told her that one of the key aggravating features of her case was making her nine-year-old son open the bathroom door to find her grandmother naked, dead and lying in a pool of blood in a bid to fix herself an alibi.
He went on to describe how Kaur then willingly let her husband Iqbal Singh become a suspect for the killing of his mum as he w3as held and quizzed by police.
Two friends , who had gone to the flat in Broadlands Road, Swaythling, to help following news of Mrs Buttar's death were also arrested and interviews suspicion of murder.
Mr Justice Burnett said Kaur had peddled lies through 14 police interviews and had gone on to change her story and admit the killing through provocation forcing a retrial.
He described how the consequences were “tragic in so many ways for so many people.”
And he added: “The precise circumstances of what occurred are known only to you. You lost your temper and completely lost your self control. The attack which followed was a frenzied one with perhaps 20 blows to her head and elsewhere on her body.
“You did nothing to help her, your actions afterwards were cruel and calculated.”
Kaur admitted manslaughter, but was yesterday found guilty of murder.
