The BJP is set to gain two Rajya Sabha seats through by-elections from Haryana shortly, which would take its strength from 43 to 45 in the 245-member House.
One seat fell vacant last August after former AICC general secretary Birender Singh quit the Upper House as well as the Congress in order to join the BJP.
The second vacancy would occur next week with Indian National Lok Dal (INLD) member Ranbir Singh Prajapati planning to put in his papers.
Prajapati has been elected to the Haryana Assembly from the Nalwa constituency of Hisar district, defeating Chander Mohan of the Haryana Janhit Congress.
“I have opted for the assembly,” Prajapati told The Indian Express on Saturday, adding that he planned to get here on Monday to submit his resignation to Vice-President and Rajya Sabha Chairman Mohammad Hamid Ansari. He said, “People of my area have reposed their faith in my defying all odds and there is no way I can betray them.”
Prajapati has been already made the chief whip of the INLD group in the Haryana Assembly.
Prajapati, as also Birender Singh, were elected to the Rajya Sabha for a six-year term back in 2010. Their term would have come to an end in August 2016.
