Kumar also had a luncheon meeting with Delhi Chief Minister Arvind Kejriwal and went for a brief chat with RJD chief Lalu Prasad on his second visit to the national capital after reassuming the chief minister's post in February after replacing Jitan Ram Manjhi.
He held interactions with a number of opposition leaders at a time when merger talks for Janata Parivar outfits are on and a larger opposition unity has been visible on the land acquisition Bill issue.
There was no word on what transpired in the meeting between Gandhi and Kumar, which has come at a time when both Congress and JD-U along with other Opposition parties have taken a strong stand against the land Bill.
