Concert promoters are battling to block pop legend Michael Jackson's series of live concerts in London this summer, accusing the star of breaking an earlier agreement to make his comeback with them.
The pop superstar is currently preparing to take to the stage in London for his first gigs since 2001, a run of 50 dates at the city's O2 Arena, starting July.
But bosses at All Good Entertainment are seeking to block the shows, reports contactmusic.com.
They are insisting they had in 2008 entered into an agreement with Jackson's manager, Frank Dileo, promising the star would appear with his sister Janet Jackson and their brothers on tour.
Jackson was allegedly prohibited from making another concert deal for 18 months as part of the contract, but he violated the clause when he signed up for the London concert series.
The promoters have now sent a cease and desist letter to Jackson's London concert organisers.
