Michael Adebolajo, 29, together with Michael Adebowale, 22, mowed down Fusilier Rigby in car, before hacking him to death in Woolwich, south east London, in May last year.
Adebolajo was condemned to die behind bars - with judge Mr Justice Sweeney saying the killer had 'no real prospect of rehabilitation'.
However, Adebowale was sentenced to a minimum of 45 years in jail because of his younger age, mental health problems and 'lesser role' in the 25-year-old father-of-one's murder.
Oh, hell. This is England. They’ll probably end up turning him loose, and then being shocked, shocked when he hacks off the head of his parole officer at their first meeting.
