"The NDA alliance is intact. Alliance gives constituents freedom to express opinion on any issue and there is no harm in this," Kumar told reporters.
Asked about the fate of the NDA if Gujarat Chief Minister Narendra Modi is projected as the Prime Ministerial candidate by the BJP, Kumar said "We should not talk in terms of ifs and buts."
On reports of him snubbing BJP MP Kirti Azad at Darbhanga, Kumar said "I am shocked to see such things in the media ... Nothing like this happened ... The issue has been blown out of proportion.
"It is the priority of the government whether to invite an MP to such a meeting," he said on Azad's allegation that as a public representative he was not allowed to raise issues related to water-logging.
Asked about his 'who has seen the future' remark which triggered speculation about possibility of a parting of ways between the JD(U) and BJP, Kumar replied that he had said so in a general context.
