Nitish Kumar is trying hard for unity amongst most opposition parties to ensure a contest 'one versus one' in parliamentary elections source says. The CM of Bihar has already held discussions with almost all regional leaders as well national leaders, including those of Congress during the last some months source says. His meeting with all the leaders has paved the way for the formation of one platform to challenge the BJP source says. It’s also planned to have a meeting at Patna, where all the leaders of different parties and small parties willing to join a common platform will likely participate source says. The presence of Sharad Pawar, Mamta Banerjee, Akhilesh Yadav, and Hemant Soren in the meeting is likely to make a lot of difference and seems the hard work of Nitish Kumar will take shape source says. There is every possibility that one coordinator is also to be announced during the meeting source says.
