Karnataka bypolls: CM BS Yediyurappa celebrates with his son BY Vijayendra
The ruling BJP swept the by-elections winning 12 of the total 15 seats, helping the four-month-old B S Yediyurappa government to retain majority in the Assembly.
Congress Legislature Party leader Siddaramaiah and State Congress chief Dinesh Gundu Rao quit their posts after the party posted a poor show, winning only two seats, as against the 12 it had held of the 15 which went to the bypolls on December 5.
The bypolls, held on December 5, were necessitated after 17 rebel Congress and JD(S) MLAs were disqualified after their revolt against the H D Kumaraswamy-led coalition government in July. The collapse of the coalition led to the BJP coming to power. Twelve of the 15 seats were held by the Congress and three by JD(S).
