Collinge took two men back to the £400,000 UK house she shared with her husband Clifford Collinge, 17 years her senior, with the promise of sex.
As they approached the property, she told Stephen Shreeves, 40, and 27-year-old Kelvin Dale that she ‘hated’ her husband, and asked if they knew anyone that could kill him.
Once there, the men launched a savage attack on the 61-year-old retired newsagent which left him with 46 separate injuries.
Collinge, who was out of the house at the time buying cocaine, returned to the house in Mansfield, Nottinghamshire, to find her husband lying in a pool of blood – but stepped over his body instead of calling an ambulance.
Help was only summoned half-an-hour later by a worried friend of 44-year-old Collinge who she had spoken to on the phone.
Prosecutors said that if there had not been a delay in dialling 999, Mr Collinge may have survived.
Following a four-week trial, a jury of five women and seven men found Collinge, Shreeves and Dale guilty of Mr Collinge’s murder.
Collinge was today jailed for a minimum of 23 years, while Stephen Shreeves, 40, and Kelvin Dale, 27, were each jailed for 18 years.
