An estimated 70 lakh citizens of Bangalore will decide the fate of 1342 candidates in 198 wards in the city.
The Sunday election, the third major poll in Karnataka in two years, is seen by the three major parties as a prestige issue.
The BJP is contesting in 197 wards, the Congress in 196 and JD-S in 194. The rest of the candidates are independents or belong to smaller parties.
All three parties have promised 24-hour power and water supply, better roads, drainage, street lights, slum clearance and other welfare measures to woo the voters.
The elections to the Bruhat Bengaluru Mahanagara Palike or Greater Bangalore City Corporation are being held after a three-year delay.
Over 30,000 policemen have been deployed in the city to ensure peaceful polling in over 6,400 polling booths.
Vote counting will take place on Apr 5, 2010.
