Bihar Chief Minister Nitish Kumar, whose Janata Dal United has suffered a body blow in the state elections due to the Chirag Paswan factor, Thursday said he has left the decision regarding the Lok Janshakti Party chief to the BJP. The decision on who will be the Chief Minister has to be taken by the NDA, he said in response to a question, indicating that the issue might be revisited despite the BJP's earlier assurances that he would retain the post.
