A jealous husband strangled his estranged wife as her children slept upstairs, then made himself a cup of tea while waiting for police.
Mohammed Anhar Ali bought cables to murder Nazia Begum at their former marital home in Bow, east London after she asked for a divorce in October last year.
In a chilling 999 call he made after the murder, Ali calmly told the operator he'd 'accidentally' killed his wife 'with a scarf'.
When police arrived he asked officers to be quiet because his daughter, and Ms Begum's daughter from a previous relationship, were sleeping upstairs.
Following his conviction for murder yesterday, Ms Begum's mother released a heartbreaking statement describing the impact the killing has had on the young girls.

The victim's mother, Janahara Begum, said: 'The day Nazia died was the worst day of our lives. Our hearts are broken beyond repair; we will never be the same again. He took away, not just my child, but a mother, a sister, a niece, a granddaughter, a cousin and a friend.
'I have to listen to my grandchildren hold each other and cry for their mother every day. How do I explain to a three year old that her mother is dead? That my child is dead?
'I took Mohammed in as my son and instead he left my heart empty by taking away my child. Her daughters will never see their mother again, they will never feel their mother's comfort again and they will never feel their mother's love, ever again.
'Every day, when the children ask me when their mother will come back from heaven, my shattered heart breaks a little more.'
