London, August 19 : Michael Jackson's mother is reportedly planning to file a lawsuit against the concert promoters of her late son, believing them to be responsible for her son's death.

Katherine Jackson apparently thinks the music legend was killed by the pressure to perform for the 50-show run in London.

She may also sue the singer's personal physician Conrad Murray, who is the focus of a manslaughter probe, after he admitted administering the sedative Propofol via an IV drip to help the King of Pop sleep.

"The possibility of a wrongful death action has been floated," the Daily Star quoted family lawyer Burt Levitch as saying.

"Dr Murray's name has been floated because he is under investigation," he added.

A spokesman for concert promoters AEG said: "It would be inappropriate to speculate on any potential litigation.'' (ANI)
