London, Oct 1 (ANI): Michael Jackson's daughter Paris believes that her father buckled under the strain of preparing for his huge 50-show 'This Is It' tour, it has emerged.

Paris, 11, has reportedly told her aunt La Toya that gig bosses worked her father into an early grave, reports The Mirror.

She confided: "The cardiologist was the best, so how could this happen? What happened is they worked him too hard.

"He never got the chance to rest. It was non-stop work."

La Toya will make the shocking claim on Channel 4's The Paul O'Grady Show.

She will tell Paul how Paris laid bare her suspicions in a hospital after his death in June.

La Toya, 53, reveals: "She said, 'No, you don't understand. They kept working him and Daddy didn't want that, but they worked him constantly'. I felt so bad."

The King of Pop planned 10 London gigs this summer but just weeks before he died he voiced fury that it had been raised to 50.

He died from a cocktail of drugs on June 25, which a coroner has ruled was homicide. (ANI)
