President of Singapore
The eighth and current president, Halimah Yacob, took office on 14 September 2017, becoming the first president elected as she was the sole eligible candidate under the new reform terms which took effect earlier that year. She is also the first female President of Singapore.
Tony Tan
On 22 December 2010, Tan announced that he would step down from his government-linked positions at GIC and SPH to run for the office of President of Singapore. Tan's campaign stressed his independence and his divergent views from the PAP government in specific policies, citing a remark made by East Coast GRC MP Tan Soo Khoon in 2005: "It is probably the first time that I have heard Cabinet Ministers, starting with no less than the Deputy Prime Minister, Dr Tony Tan, expressing divergent views [on the Integrated Resorts question]." However, competing presidential election candidates and former PAP members Tan Kin Lian and Tan Cheng Bock questioned Tan's independence from the party. On 7 July 2011, Tony Tan submitted his presidential eligibility forms.
