Publication of the result of Michael Jackson's post-mortem is to be delayed until after police have finished their investigation into his death.

The Los Angeles County Coroner's Office said it had now completed its examination of Jackson's body and related toxicology tests.

But police have asked the office not to release any findings while their investigation is ongoing.

Post-mortem examination results are widely expected to show that Jackson was on heavy medication when he died at his rented Beverly Hills home on June 25.
