Seat-sharing formula for the 2019 general elections has been finalised by the NDA constituents in Bihar, with the BJP getting the lion's share of 20 out of the 40 Lok Sabha seats and the rest going to its allies including the JD-U, LJP and the RLSP, party leaders said on Thursday.

Although a formal announcement in this regard is yet to be made, a senior Bharatiya Janata Party (BJP) leader said: "BJP would contest 20 seats, JD-U 12, LJP five, RLSP two and a splinter group of RLSP one seat."
