Nitish Kumar urges Sonia to take lead in challenging BJP for Presidential candidate
Kumar made the appeal to the Congress chief during a visit to her 10 Janpath residence in Delhi on Thursday.
The Presidential election is due in July this year.
"JD-U wants that for the presidential polls, Mrs Gandhi should take the lead in fielding a united candidate of the opposition," Janata Dal leader KC Tyagi said after Kumar's meeting with Gandhi.
Kumar's Janada Dal-U and Congress are allies in Bihar.
The move is being seen as an attempt to extend the alliance to the national level before the 2019 general elections.
NDTV quoted its sources as saying that Nitish Kumar suggested Sonia Gandhi that, "Instead of reacting to Narendra Modi, we should be setting our own agenda."
