Presidential elections were scheduled to be held in Singapore on 17 August 2005. 21 application forms for the Certificate of Eligibility required to contest were collected, and forms were submitted by four candidates. After considering the candidate's applications, the Presidential Elections Committee issued only one Certificate of Eligibility to the incumbent, Sellapan Ramanathan.[1]
S.R. Nathan was the only candidate to stand nominated and thus was re-elected uncontested due to the lack of other eligible candidates. S.R. Nathan previously served as Singapore's Ambassador to the United States from 1990 to 1996. He continued his second term as the sixth President of Singapore.
