Charlotte Dootson, 25, murdered her boyfriend Mohammed Mukhtar by tying him up and strangling him with an extension lead while she flirted and sexted with her new man.
On Tuesday, she was jailed at Manchester Crown Court for life and ordered to serve a minimum of 22 and a half years in custody before she can be considered for parole.
She smirked on videolink throughout the hearing and grinned and gave a thumbs up as her victim’s family described their anguish at losing him.
