Barisan Sosialis
In early October 1966, he and eight other Barisan Sosialis MPs boycotted the Parliament over the decision by the ruling People's Action Party (PAP) to split from Malaysia. This was part of the Barisan's strategy to protest "undemocratic acts" of the Government, by carrying their struggle against the PAP outside of Parliament. He declared that the means of the struggle would be "street demonstrations, protest meetings, strikes".
