A Las Vegas promoter has poured scorn on reports Michael Jackson is planning a Las Vegas spectacular - insisting the pop superstar is incapable of performing ever again.

Jackson prompted speculation he would headline his own Sin City residency when an equity group linked to the Las Vegas Hilton helped him save his Neverland Ranch from foreclosure.

He has also made a number of personal appearances in the Nevada city of late - including at an Ultimate Fighting Championship match on Saturday.

But promoter Jack Wishna - who helped Celine Dion secure her successful stint in Las Vegas - insists Jackson isn't fit enough to return to the stage.

He tells the National Enquirer, "Sadly, Michael's incapable of keeping promises, because he hasn't got the will to even show up anywhere, much less get himself into shape for a world-class performance. He might drop by to wave at guests, or do a dance on top of a limo, but a longterm show? That dream will never come true, I'm afraid."
