Gangtok: Independent candidate RN Chamling won Rangang-Yangang Assembly seat by 708 votes defeating his nearest Sikkim Democratic Front (SDF) nominee Kumari Mangar in Sikkim.
While Chief Minister Pawan Kumar Chamling's younger brother RN Chamling, who fought the seat as an Independent candidate polled 4,788 votes, Kumari Mangar of ruling SDF got 4080 votes.
BJP's Bikash Basnett came third with 351 votes.
Bishnu Prasad Adhikari of Congress finished last with only 28 votes, less than 46 votes cast under NOTA.
The by-election was necessitated following relinquishing of the seat by the Chief Minister as he retained Namchi-Singithang constituency which he had also won in the last Assembly Election.
