27 April 1955 when the police used force on them, injuring 15 people. In response, Fong Swee Suan, Lim's former classmate at The Chinese High School, and now the leader of the Bus Workers' Union and a PAP member, was quoted in the Chinese newspapers that "there was bound to be bloodshed in a revolution". Students from the Chinese-medium schools also joined the strikes in droves to provide moral support. Chief Secretary William Goode had suggested that the demand for bloodshed by the PAP was the cause of the violence. Chief Minister David Marshall demanded in the Legislative Assembly that the PAP "purge themselves of the communists", whom he placed at fault for the riots. Lim refrained from commenting at length during the debate, except to state that he would not support the view that was put forth by the British.

Knowing that Marshall had made an enormous gamble by placing his job on the line in the case the talks failed, his political rivals - particularly from the PAP and the Labour Party - seemed to have given up on helping Marshall achieve his objective. Marshall's key desire was for the British to
