Lakhvir Singh, 45, killed Lakhvinder Cheema, 39, because she could not bear the thought of him getting married to a younger woman.
Cheema died hours after eating a leftover curry which had been in the fridge of his home in west London last January while his fiancee Gurjeet Choongh, 21, was violently ill.
Singh had earlier gone into the house and poisoned the dish with the deadly poison aconite, known as the Queen of Poisons. It was the first time the poison had been used to kill in England since 1882.
She was jailed for life yesterday at London’s Old Bailey and told she must serve a minimum of 23 years behind bars after being found guilty of murder, the Press Association reported.
