In Eastern Bloc politics, the split with Yugoslavia led to the denunciation and prosecution of alleged Titoists designed to strengthen Stalin's control over the bloc's communist parties. They resulted in show trials of high-ranking officials such as Xoxe, General Secretary of the Communist Party of Czechoslovakia Rudolf Slánský, Hungarian interior and foreign minister László Rajk, and General Secretary of the Bulgarian Workers' Party central committee Traicho Kostov. Furthermore, Albania and Bulgaria turned away from Yugoslavia and aligned themselves entirely with the USSR. Regardless of DSE dependence on Yugoslav support, the KKE also sided with the Cominform, declaring its support for fragmentation of Yugoslavia and independence of Macedonia. In July 1949, Yugoslavia responded by withholding further support to the Greek guerrillas and the DSE collapsed almost immediately.
