A British mother mouthed 'I love you' as her husband battered her to death with a wheel brace before burying her body in their back garden, a court heard.
Ahmed Dawood Seedat, 37, killed Fahima Yusuf - originally from Bolton - while their children slept at their home in Perth, Western Australia in August.
Accountant Seedat, 32, murdered his wife because he wanted a relationship with her sister.
Today, a judge in Australia sentenced him to 23 year behind bars and called the killing brutal, callous and cowardly.

Justice Bruno Fiannaca said Seedat planned the murder of Ms Yusuf for weeks and had egotistical motives.
Justice Fiannaca said Seedat had earlier searched online for chilling terms such as 'cremating a body', 'best place to knock someone out' and burying someone alive.
He said Seedat struck his wife of eight years with a wheel brace as she slept.
Seedat's lawyer Bernard Standish previously told the court his client had lost attraction for his wife and that he could no longer meet her 'sexual demands'.
Seedat told police officers on the night of the murder that he killed her because she tried to come on to him, the court heard.
He had claimed his wife became 'sexually aggressive', prompting him to attack, but Justice Fiannaca said that was implausible, reports the Canberra Times.
Ms Yusuf woke up after the first blow but was vulnerable and easily overpowered by him as he continued his attack, Justice Fiannaca said.
