New Delhi: The JDU wants results of the 2015 Bihar Assembly polls, in which it had fared much better than the BJP, to be a key factor while deciding how many seats each of the four NDA parties in the state will get to contest in the 2019 Lok Sabha elections.

In the Assembly election, the JDU had won 71 of the 243 seats, while the BJP had emerged victorious in 53 seats and the LJP and RLSP in two each.

The JDU was then an ally of the RJD and the Congress, before it dumped them last year to rejoin the NDA.

Formal talks over a seat-sharing formula among the NDA constituents are yet to begin and JDU leaders said the BJP should take the lead to ensure that it was done quickly to avoid any serious differences near the polls.

A BJP leader described the JDU's argument as "unrealistic" and the "usual political tactics" deployed by different parties ahead of elections.
