Congress' N Muniratna has established an unassailable lead of over 44,000 votes over his nearest BJP rival Tulsi Muniraju Gowda in the Rajarajeshwari Nagar assembly constituency here, as per trends available after the first three hours of counting.
Officials said Munirathna has secured 75,282 votes, followed by Gowda with 31,182 votes.
The Congress' ruling coalition partner JD(S)' G H Ramachandra had polled 23,526 votes.
Assembly elections across the state were held on May 12.
However, polling in Rajarajeshwari Nagar was deferred to May 28 following a voter ID controversy and other irregularities.
A major row had erupted over electoral malpractices and seizure of nearly 10,000 voter ID cards from an apartment in the constituency, ahead of the May 12 elections.
Muniratna had won the seat in the previous assembly.
