Journalist Martin Bashir, whose documentary on Michael Jackson is due to be shown tonight, has described the star as 'a disturbing individual'.
The profile, which is due to be broadcast on ITV1 tonight, shows Jackson going on a $6 million shopping spree in Las Vegas buying everything from 10ft-tall glass urns to over-sized marble chess sets.
Bashir was granted unprecedented and exclusive access to the star for eight months to make the 90-minute show 'Living With Michael Jackson'.
Bashir has described the singer as, 'A disturbing individual whose financial power enables him to do what he wants when he wants.'
Bashir also filmed Jackson just half an hour after he dangled his then 9-month-old son Prince Michael II from a 100ft-high hotel balcony in Berlin last November.
'Not one of his entourage was prepared to tell him what he had done was ludicrous and dangerous,' he said.
In the US, ABC won a network bidding war for the documentary and are set to screen it on Friday.
The New York Daily News has quoted unidentified television executives who estimate that the station paid between $4m and $5m for rights to screen the programme.
