Counting of votes will be held on Sunday in assembly polls in Madhya Pradesh, Rajasthan, Chhattisgarh and Telangana in what is seen as a semi-final contest ahead of the general elections in less than six months.
The Congress, which is in power in Rajasthan and Chhattisgarh, and the BJP, which is ruling Madhya Pradesh, are locked in a straight fight in these three states, while K Chandrashekhar Rao-led Bharat Rashtra Samithi (BRS) is hoping for a hat-trick in Telangana.
Pollsters have been divided on the outcome, with quite a few exit polls putting the BJP ahead in Madhya Pradesh and giving it an edge in Rajasthan while predicting that Congress has an advantage in Telangana and Chhattisgarh.
