Former Honduran President Rafael Callejas pleaded guilty in New York on Monday to conspiracy to commit racketeering and wire fraud in connection with the FIFA corruption scandal.

The 72-year-old Callejas, who has been on bail in the United States since leaving Honduras by private jet late last year to face justice, will be sentenced on August 5.

The two counts each carry a maximum sentence of 20 years in jail.

"Guilty," Callejas told Magistrate Judge Robert Levy in a US federal court in Brooklyn, entering his plea. He spoke calmly in fluent English with a US accent, dressed in a dark suit.

Callejas, who served as president of Honduras from 1990 to 1994 and was head of the country's football federation until last August, had faced eight US charges of racketeering, fraud and money laundering.

As part of Monday's plea, he has agreed to forfeit $650,000: $180,000 to be paid within one week and the balance due within 12 months, prosecutors said during the 25-minute hearing.
