Congress legislator from Rajkot East Indranil Rajyaguru said he would fight against Rupani in the latter's constituency of Rajkot-II.
"I have decided to contest the 2017 Assembly polls against Vijay Rupani and expose the corrupt practices of the BJP government," he told a press conference where the BJP's former RMC (Rajkot Municipal Corporation) standing committee chairman Rajbha Zala officially joined the Congress.
No political party, including the Congress, has finalised the names of candidates for the polls due next year.
"I was feeling uncomfortable in the BJP as they wasted money on false achievements and promoted corruption.
"After spending many years in the party, I know how it works during the polls and in the next Assembly election, I will try to use that experience and work for the Congress," Zala said.
