Lee Kuan Yew, Singapore's first Prime Minister, was appointed as Senior Minister in 1990, after being succeeded by Goh Chok Tong as prime minister. He was ranked second in the order of precedence, superseding the incumbent Deputy Prime Ministers Lee Hsien Loong and Ong Teng Cheong.

Goh Chok Tong was appointed Senior Minister in 2004 after handing over the office of Prime Minister to Lee Hsien Loong. As Senior Minister, he was ranked second in the order of precedence, while Lee Kuan Yew, who was appointed as Minister Mentor, ranked third in the order of precedence.

S. Jayakumar relinquished his role as Deputy Prime Minister in 2009 and was appointed as Senior Minister before retiring from politics in 2011.

After the 2011 general election, Minister Mentor Lee Kuan Yew and Senior Minister Goh Chok Tong left the Cabinet but remained as Members of Parliament.

On 8 June 2023, Tharman Shanmugaratnam announced his intention to run for the 2023 presidential election and his scheduled resignation on 7 July 2023 from all his positions in the government and as a member of the People's Action Party, as the presidency is a non-partisan office.
