A day after five of six MLAs of Bihar Chief Minister Nitish Kumar's Janata Dal (United) in Manipur joined the ruling BJP, a war of words over each other's political decimation has ensued between the former coalition partners. Bihar BJP MP and Nitish Kumar's former long time deputy Sushil Kumar Modi last night taunted the JD(U) over its MLA switching sides, and said the party will collapse in Bihar as well very soon.
