In late 1942 and early 1943, the PPR experienced a severe crisis because of the murder of its first secretary Marceli Nowotko. Gomułka participated in the party investigation directed against another member of the leadership, Bolesław Mołojec, that resulted in Mołojec's execution. Together with the promoted to secretary Finder and Franciszek Jóźwiak, "Wiesław" (Gomułka) was included in the Party's new inner leadership, established in January 1943. The Central Committee was enlarged in the following months to include Bolesław Bierut, among others.
