Bihar chief minister Nitish Kumar will host a meeting of opposition parties at his official residence on Friday which is expected to set the tone for the much-hyped ‘Opposition unity’ to take on the Bharatiya Janata Party (BJP) in next year's Lok Sabha elections. More than a dozen parties are expected to join the crucial meeting called by the Janata Dal (United) chief, who snapped ties with the BJP last year. The meeting is aimed at boosting the Opposition’s morale which has been hurt by the frequent squabbling and infighting of parties.
