Sharma joined the party yesterday, becoming the third former MLA to join RLD recently. The other ex-MLAs who came to RLD's fold were former Uttar Pradesh Minister Yograj Singh and ex-MLA of BSP from Kandhla constituency Balbir Singh Kiwana.
Sharma, who was reportedly close to Congress's former state chief Rita Bahuguna and himself was the party's state vice-president, told PTI he would fight the 2017 Assembly polls in Uttar Pradesh.
However, the constituency would be decided after discussion with the party leaders, he said.
