Abakumov had headed SMERSH from 1943 to 1946; his relationship with Beria involved close collaboration (since Abakumov owed his rise to Beria's support and esteem) but also rivalry. Stalin had begun to encourage Abakumov to form his own network inside the MGB to counter Beria's dominance of the power ministries. Kruglov and Abakumov moved expeditiously to replace Beria's men in the security apparatus with new people. Very soon, Deputy Minister Stepan Mamulov of the Ministry of Internal Affairs (MVD) was the only close Beria ally left outside foreign intelligence on which Beria kept a grip.
