Nitish Kumar, chief minister of the large state of Bihar, in northern India, has just formed a regional government with the support of Narendra Modi's BJP. Two years ago, Nitish Kumar severed his ties with the Hindu nationalist party and joined the opposition forces led by the Congress party.

The Congress, the only national formation in this group, cannot agree with its regional allies on a distribution of seats. Without this distribution, the opposition will arrive divided in April, which will benefit the BJP.
