Lim Yew Hock
Marshall lost his seat in Cairnhill Single Member Constituency to Lim Yew Hock, the Chief Minister, in the 1959 general election as a WP candidate, but won in Anson Single Member Constituency in the 1961 by-election. He resigned from the Workers' Party in January 1963 after a spat with the party. After losing his seat again in the 1963 general election as an independent candidate, he returned to practice law and remained active in politics even after J. B. Jeyaretnam became the leader of the WP in 1972.
