For years, Sean “Diddy” Combs was a music mogul unlike any other; once described as a “zeitgeist-dominating colossus” who helped hip hop become a global cultural force. But peppered throughout his years of living to extraordinary excess, were allegations of violence, and misconduct. He managed to escape much time in custody, until September, when he became inmate 37452-054 at a Brooklyn detention centre, after he was charged with federal crimes.

Today, we speak to North America correspondent Michael Koziol, who’s on the ground in New York City, where he has attended the first day of Diddy’s trial, and learned what the prosecution, and defence, plan on arguing in one of the biggest celebrity trials of the decade.
