Michael Jackson's former doctor should have his medical license restricted while he faces charges over the singer's death, according to California's attorney general.

Dr Conrad Murray returned to work last month after pleading not guilty to a charge of involuntary manslaughter.

Under the conditions of his bail, Dr Murray can continue practising medicine, but is prohibited from administering certain drugs.

The list of banned substances includes Propofol, which was one of the drugs blamed for Jackson's sudden death last June.

However, in a petition filed on Tuesday Edmund Brown argued that Dr Murray had shown “poor professional judgment” while working for Jackson.

He called on the California Medical Board to rescind Dr Murray's license and “take measures to protect the public from future harm”, reports the BBC.

Meanwhile, reports earlier this week appeared to shed new light on Dr Murray's actions in the hours up to Jackson's death on June 25.

However, the claims, which include an accusation that he halted CPR to hide drug vials, have been played down by his lawyer.
