The surprise announcement of Choudhary has left local BJP workers confused as they have been opposing him for over two decades.
However, when asked whether he would extend support to BJP if he wins the elections, Singh said it was a hypothetical question.
On joining any political formation, Singh said he would take the decision after consulting his electorate.
“When I win this election, if the question of my any other political affiliation arises, I will come back to this land and its people and ask them what they want me to do as they would have sent me to Parliament,” he said.
Singh said he is a nine-time MP and in each term he followed the instructions of senior party leaders like Bhairon Singh Shekhawat to contest from particular seat, but this being his last election, he wanted to serve the area where he was born.
