In 1961 Pracheachon's spokesperson, Non Suon, criticized Sihanouk for failing to tackle inflation, unemployment, and corruption in the country. Non Suon's criticisms gave Sihanouk the impetus to arrest Pracheachon leaders, and, according to him, he had discovered plans by their party to monitor local political developments on behalf of foreign powers. In May 1962 Tou Samouth, Pracheachon's secretary-general, disappeared, and its ideological ally, the Communist Party of Kampuchea, suspected that Samouth had been secretly captured and killed by police. Sihanouk nevertheless allowed Sangkum's left-wing politicians to run again in the 1962 general elections, which they all won. He even appointed two left-wing politicians, Hou Yuon and Khieu Samphan, as secretaries for planning and commerce, respectively, after the election.
