Bangalore: The Congress dealt a massive blow to the Bharatiya Janata Party (BJP) in Karnataka urban local body elections by winning four major city corporations. The Congress not only made huge gains by winning the highest number of wards across the state, but the party also routed BS Yeddyurappa's Karnataka Janata Party (KJP) and ended the rule of Reddy brothers in Bellary by decimating their BSR Congress across central Karnataka.
