Two Barisan Sosialis Members of Parliament, Chia Thye Poh and Koo Young, were charged with sedition after publishing the 11 December 1965 issue of the "Chern Sien Pau", the Chinese edition of the party organ "The Barisan", which claimed that the People's Action Party government was "plotting to murder" Lim Chin Siong, a left-wing politician who had founded the Barisan Sosialis. On 26 July 1966, the defendants were found guilty and sentenced to a fine of $2,000 each. They appealed against their convictions but subsequently withdrew the appeals.
