Kumar is here to attend the two-day national executive and council meeting of JD(U) that began today in which a number of state chiefs of his party complained of being ignored and harassed by BJP, the lead NDA party.
During the dinner meeting, Kumar and Singh discussed ways to improve the coordination between the two parties.
Kumar was accompanied by party spokesperson K C Tyagi who earlier in the day said there was no question of aligning with "enemy" Congress by dispensing with "friend" BJP.
On the first day of the party's marathon meet, JD(U) made it clear that though it has strong reservations against Narendra Modi's projection as BJP's Prime Ministerial candidate, it did not want to leave NDA and won't press for a timeline on the latter to announce its PM candidate.
