Bhopal, April 16: It has been over a month since Chief Minister Shivraj Singh Chouhan launched the Ladli Behna Yojna to target the crucial 48 per cent women s vote in the year-end assembly elections in Madhya Pradesh. Calling it a step towards the economic empowerment of poor women, the ruling BJP is leaving no stone unturned to use it to neutralise the high anti-incumbency of nearly 20 years of its rule.
