A year after federal prosecutors unveiled a sweeping criminal case against Sean "Diddy" Combs and months after a trial that revealed shocking details of violence and his private life, the convicted music mogul will learn his sentence.

He could face up to two decades behind bars, but his attorneys are battling for a more lenient sentence that could see Combs freed in a matter of weeks – or acquitted.

In July, a jury acquitted him of the most severe charges: racketeering and sex trafficking. But he was found guilty of two counts of transportation to engage in prostitution. Each count carries a maximum sentence of 10 years in prison.

Prosecutors have asked for a minimum of 11 years, but Combs' lawyers have argued that such a sentence would be a dramatic overreach.

"In plain terms, prosecutors want to see Diddy defined by the worst-case math, while the defence wants the judge to cut through it and impose something far lighter," said Todd Spodek, a New York attorney who once represented fake heiress Anna Sorokin.
