Michael Jackson's personal (physician), Conrad Murray, has gone on trial in Los Angeles, charged with involuntary manslaughter of the singer.
(Prosecutors) said he acted with "gross negligence" and gave Jackson a (lethal) dose of the sedative propofol that caused his death in June 2009.
The (defence) said Jackson gave himself too much of the drug, a sleeping aid.
Dr Murray, 58, who (denies) the charge, could face four years in jail and the loss of his medical licence.
