Cardinal Jaime Sin, who helped lead peaceful revolts that ousted two Philippine presidents, retired Monday as archbishop of Manila, the Vatican said.
Pope John Paul II accepted Sin's resignation submitted for reason of age. He turned 75, the normal retirement age for bishops, on Aug. 31.
As Sin's successor, the pope named Archbishop Gaudencio B. Rosales, who has been serving as archbishop of Lipa.
Sin has been ailing in recent years, suffering from kidney problems and diabetes.
Sin played an influential role in the "people power" uprising that led to the ouster of Ferdinand Marcos in 1986. He also led large street protests that led to the ouster of President Joseph Estrada over alleged corruption and misrule two years ago.
