Michael Jackson's family are preparing to share hundreds of private emails from concert promoters AEG, as part of the ongoing wrongful death trial.

The emails, sent by AEG, apparently detail Jackson's deteriorating health and inner turmoil in the days leading up to his death - as he struggled to prepare for the final series of concerts at London's O2 Arena.

One email from Randy Philips, a promoter for AEG, reads, "This is the scariest thing I have ever seen. He is an emotionally paralysed mess riddled with self-loathing and doubt now that it’s show time. He’s scared to death."

This morning sees the opening statements being made, and the trial is expected to last up to three months. It could include testimony from Jackson's two eldest children, Paris and Prince, as well as Diana Ross, Prince and Jackson's two ex-wives - Lisa Marie Presley and Debbie Rowe.

The £26.5billion suit accuses AEG of hiring Dr Conrad Murray, who was found guilty of manslaughter in 2011. Murray gave the fatal dose of propofol to Jackson that led to his death.

The Jackson family complaint alleges, "AEG had legal duties to Michael Jackson to treat him safely and to not put him in harm’s way. But AEG, despite its knowledge of Michael Jackson’s physical condition, breached those duties by putting its desire for massive profits from the tour over the health and safety of Michael Jackson."

Philips also wrote in an email after Jackson's death, "Michael’s death is a terrible tragedy, but life must go on. AEG will make a fortune from merch sales, ticket retention, the touring exhibition and the film/dvd."

AEG went on to earn about £160million from the film This Is It, which featured rehearsal footage from Michael Jackson. Their lawyers will claim that Murray was hired by Jackson, and not by AEG.
