He then took on the newly created role of Senior Minister in 1985, before his retirement in 1988.
Lee Kuan Yew was the country’s first Prime Minister. Upon his handover to Goh Chok Tong in 1990, he was appointed Senior Minister by his successor. He was ranked second in the order of precedence, superseding the country’s sitting Deputy PMs.
