Mexican drug lord, Ismael 'El Mayo' Zambada, has entered a guilty plea to two drug smuggling and conspiracy charges in a court in New York, bringing an end to one of the longest and most notorious criminal careers in the history of organised crime.
Zambada was not just any drug lord.
He was the founder of the Sinaloa Cartel, for years the biggest and most powerful criminal organisation in Mexico - with an astonishing global reach.
Last year, he pleaded not guilty to a raft of drug smuggling, gun-running and money laundering offences. But now, he has changed his plea before a federal judge in Brooklyn.
In doing so, he officially accepted his role in creating the vast criminal network which has sent huge amounts of cocaine and other drugs into the US since he co-founded the cartel at the end of the 1980s.
