BJP has announced that the party’s spokesperson Sudhanshu Trivedi and former Lok Sabha MP Satish Dubey will contest for these two Rajya Sabha MP posts from Uttar Pradesh and Bihar respectively.
Samastipur in Bihar will go for by polls due to the demise of Ramchandra Paswan who won from this seat on behalf of LJP in 2019 elections. Congress has nominated Dr. Ashok Kumar to contest from this seat. Earlier during the last elections, he lost to Ramchandra Paswan.
