Self-government (1955 – 1963)
The leader of the Labour Front, David Marshall, became the first Chief Minister of Singapore. He presided over a shaky government, receiving little cooperation from either the colonial government or the other local parties. In May 1955, however, the Hock Lee Bus Riots broke out, killing four people, and consequently would later seriously discredit Marshall's government. In April 1956, he led a delegation to London to negotiate for complete self-rule, but the talks fell through due to British concerns about labour unrest and communist influence. Marshall continued to pressure the British, before declaring that if the British did not give Singapore self-rule, he would resign. However, the British were not concerned about his resignation, and because he did not want to back out on his word, Marshall eventually resigned. His successor as Chief Minister, Lim Yew Hock, launched a crackdown on communist and leftist groups, imprisoning many trade union leaders and several pro-communist members of the PAP under the Internal Security Act.
The British government approved of Lim's tough stance against communist agitators, and when a new round of talks was held beginning in 1957, they were amenable to granting almost complete self-government. A State of Singapore would be created, with its own citizenship, consisting of persons born in Singapore or the Federation of Malaya, British citizens of two years' residence, and others of ten years' residence. The Legislative Assembly would be expanded to fifty-one members, entirely chosen by popular election, and the Prime Minister and cabinet would control all aspects of government except defence and foreign affairs. The British-appointed Governor was replaced by a Yang di-Pertuan Negara or head of state.
