In the April assembly polls, the SDF had bagged Poklok-Kaamrang and Martam-Rumtek, while Gangtok was won by SKM. The by-polls had to be held as the sitting legislators put in their papers, each having won from another seat.
The BJP and SKM had contested the bypolls by entering into a seat adjustment. While the saffron party fielded candidates in two seats, it backed Sikkim Krantikari Morcha president Golay in Poklong- Kaamrang.
This is the first time the BJP has won an assembly contest in Sikkim where it got only 1.62 per cent votes in the April polls. However, it had opened its account in the legislature in August, when 10 SDF MLAs joined its fold.
In the 32-member Sikkim assembly, the ruling SKM now has 19 legislators, followed by BJP (12) and SDF (1).
The April assembly polls saw the SKM coming to power with 17 seats, two more than SDF, whose long rule lasted about 24 years and six months.
Two SDF MLAs had crossed over to SKM in August.
