Narendra Modi, the BJP's candidate for Prime Minister, was frank in his opinion today of Nitish Kumar, the Chief Minister of Bihar. "The prospect of prime ministership does not let him sleep. He has such a high opinion of himself; he feels he is more qualified," said Mr Modi at a rally in Mr Kumar's state. He also predicted that his will not be the last word in this dispute. "The arrogance of some people is very high. So anything you say on their turf, till they reply they don't feel at peace."
