The former head of the Olympic Council of Ireland, Pat Hickey, has resigned from the executive board of the International Olympic Committee.
It follows the controversy surrounding ticket-selling at last year's Games in Rio de Janeiro.
Mr Hickey was arrested by Brazilian police during the Games and held in jail for almost two weeks before being released on health grounds.
The 72-year-old faces trial in Brazil in November, over an alleged scheme to sell tickets illegally.
