That same year, Kilbom launched a new Communist Party of Sweden, one that would be independent from Moscow, and became more critical of Stalin and the Soviet Union. In 1934 his party took the name Socialist Party (Socialistiska partiet). The party's supporters were generally called "Kilbommare" after Kilbom while the Comintern affiliated Communist Party members were called "Sillénare" after their party leader Hugo Sillén. The first couple of years, the Kilbom-Party was much bigger than the official Communist Party. Kilbom also managed to keep control over the communist daily "Folkets Dagblad Politiken".
