Lim Yew Hock
The successor to the Emergency Regulations Ordinance, the Preservation of Public Security Ordinance 1955 ("PPSO"), was introduced a result of the 1955 Hock Lee bus riots by the Labour Party government in Singapore. There was strong opposition to the PPSO by the party then in opposition, the People's Action Party ("PAP"). In 1958, Lee Kuan Yew of the PAP accused the Lim Yew Hock government of using the PPSO to stifle political dissent.
