Bihar deputy chief minister and RJD leader Tejashwi Yadav on Saturday said the Congress is the biggest party in the Opposition but wherever regional parties are strong, they should be allowed to sit in the "driver's seat" to take on the BJP in the 2024 general elections. Yadav also said that former Bihar chief minister Lalu Prasad and current CM Nitish Kumar along with him were making efforts to bring together regional parties and the Congress. "The Congress is part of the Mahagathbandhan in Bihar. In Bihar, we are the bigger party but the Congress is the biggest Opposition party in the country. Lalu ji, Nitish ji and all of us are making efforts that Congress and regional parties come together and to decide as to what is the way forward," Yadav told reporters in response to a question while leaving the CBI headquarters where he was quizzed for more than eight hours.
