S. R. Nathan
During the 1999 presidential election, as two other prospective candidates were found to be constitutionally ineligible, Nathan was elected unopposed as President on 18 August 1999. His candidacy was supported by Senior Minister Lee Kuan Yew and former President Wee Kim Wee. Nathan succeeded the fifth President of Singapore, Ong Teng Cheong, and was sworn in on 1 September 1999.
