Cong leader Digvijaya Singh expressed regret over not being able to cast his ballot in MP's Rajgarh, which is over 130 km away from the state capital Bhopal where he is locked in a keen contest with BJP candidate Pragya Singh Thakur. "I regret that I could not reach Rajgarh to cast my ballot. Next time, I will ensure that my vote is registered in Bhopal," Singh said.
