The International Olympic Committee said Ireland's Patrick Hickey has resigned from its executive board, more than a year after he was arrested at the Rio de Janeiro Olympics in a ticket touting investigation.
The IOC body announced Mr Hickey's resignation ahead of the board's two-day meeting which opens on Monday in Lima, Peru.
Mr Hickey "emphasised that he wants to protect the IOC", the Olympic body said, citing his resignation letter.
The IOC board seat representing the Association of National Olympic Committees (ANOC) will be elected at a four-day annual meeting starting on Wednesday in Lima.
Mr Hickey temporarily stepped aside from Olympic work after Brazilian authorities arrested him at the IOC's hotel in Rio.
He denies wrongdoing and retains his IOC membership.
Mr Hickey returned to Ireland in December after the ANOC loaned him £326,000 in bail money.
