Bihar Chief Minister Nitish Kumar and RJD supremo Lalu Prasad Yadav met Congress president Sonia Gandhi here on Sunday and pitched for bringing all opposition parties together to defeat the BJP in 2024.

The meeting at Gandhi's 10 Janpath residence is being considered very crucial in forging an opposition unity as efforts are on to reconcile differences between the Congress and some regional parties that have been at loggerheads traditionally.
