This is the highest-ever victory margin in the seat since 1972 when Mizoram began to have a separate legislature.
Ngurdingliana secured 7,005 votes out of the 13,703 votes polled while Hmar managed to bag 4,171 votes.
Polling for the seat was held on February 23.
Mizoram People's Conference (MPC) candidate Lalhmangaiha Sailo, son of former chief minister Brig Thenphunga Sailo and present chief of MPC got 1,274 to secure the third position while Zoram Nationalist Party (ZNP) nominee C Lalchhandama trailed behind with 976 votes.
Ngurdingliana is the son of former Speaker of the state legislature Dr H. Thansanga, who had won two times earlier from the constituency.
