Moulana is most noted for his orchestration of the defection of prominent members of the LTTE guerrilla group, including its one-time Military Commander Vinayagamoorthy Muralitharan (Colonel Karuna), from the terror outfit to the government in 2004. He resigned his seat in Parliament shortly thereafter due to the rising threat on his life from the LTTE. Moulana thereafter was appointed as a high-ranking diplomat at the Embassy of Sri Lanka to the United States., and upon his return to Sri Lanka in 2010, he resumed his political career by being elected as the Mayor of Eravur, and thereafter as a Member of the Eastern Provincial Council and held that position until his re-election to Parliament in August 2015.
