Michael Jackson's former doctor, Conrad Murray, has been jailed for four years, three weeks after being found guilty of killing the pop star.

Prosecutors who depicted Murray, 58, as remorseless for the superstar's death urged the judge to sentence him to four years in prison, while a defence lawyer said Murray was in a prison of self-punishment and should receive probation.

Murray has been in jail since he was convicted on November 7 of involuntary manslaughter for Jackson's fatal overdose of the anaesthetic propofol.

Prosecutors said Murray has shown no remorse for Jackson's death and has placed blame on others, including Jackson himself.

They submitted a series of post-trial media interviews with Murray on a DVD.

In one excerpt, Murray states: "I don't feel guilty because I did not do anything wrong."
