Prime Minister Narendra Modi today hit out at grand alliance in Bihar , calling it as an unnatural one, formed with the sole objective of achieving power at any cost.Addressing election meetings at Hajipur Mr. Modi reminded people that the two pillarrs of the Grand Alliance-Nitish and Lalu were abusing each other before they came together.Their coming together is sheer opportunism,Modi said,and asked people to vote for NDA to save Bihar from backwardness. <br/><br/>PM said Nitish Government was responsible for rise in the prices of pulses in Bihar as he was not taking any action against hoarders and raids were not being conducted. He asked when pulses are made available to people at rupees 120 per kg in New Delhi ,then why not in Bihar. PM said Nitish kumar must explain why action against hoarders is not being taken.
