Former Selangor Menteri Besar Mohd Khir Toyo has relinquished his posts as the state's Umno and Barisan Nasional chief.

This is the second resignation by a senior Umno leader in just a day. The first to call it quits was Umno Secretary-General Radzi Sheikh Ahmad who made his announcement this morning. Radzi also resigned as Barisan Nasional secretary-general.
