Michael Jackson 'warned about propofol use'

Singer Michael Jackson was warned by a nurse practitioner about using the sedative propofol to help him sleep, a Los Angeles court has heard.

Cherilyn Lee said Jackson told her that Dipravan - a brand name for propofol - was the only thing that would knock him out and induce the sleep he needed.

Ms Lee was testifying on Tuesday at the involuntary manslaughter trial of the singer's physician, Dr Conrad Murray.
