Lim Yew Hock
Following this, the PAP decided to re-assert ties with the labour faction of Singapore in the hope of securing the votes of working-class Chinese Singaporeans, many of whom were supporters of the jailed unionists. Lee Kuan Yew convinced the incarcerated union leaders to sign documents to state their support for the party and its policies, promising to release the jailed members of the PAP when the party came to power in the next elections. Ex-Barisan Sosialis member Tan Jing Quee claims that Lee was secretly in collusion with the British to stop Lim Chin Siong and the labour supporters from attaining power because of their huge popularity. Quee also states that Lim Yew Hock deliberately provoked the students into rioting and then had the labour leaders arrested. Greg Poulgrain of Griffiths University argued that "Lee Kuan Yew was secretly a party with Lim Yew Hock in urging the Colonial Secretary to impose the subversives ban in making it illegal for former political detainees to stand for election". Lee Kuan Yew eventually accused Lim Chin Siong and his supporters of being communists working for the Communist United Front, but evidence of Lim being a communist cadre was a matter of debate as many documents have yet to be declassified.
