"My role in the party will be given by the party President but I will work for the people," Tirath said after joining the saffron party.
Tirath's induction will be an achievement for the BJP which is on a spree to induct leaders from rival Congress and AAP as it will make the party stronger.
Reacting over Tirath's induction BJP leader Srikant Sharma said, "No one wants to contest from Congress."
Meanwhile, reacting over Tirath's hopping party Congress leader Randeep Surjewala called her 'opportunist'.
"Opportunist leaders BJP ko hi mubarak," Surjewala was quoted by ANI as saying.
Last week, former IPS officer and social activist Kiran Bedi joined BJP and later former AAP leaders Shazia Ilmi and Vinod Kumar Binny joined BJP.
Days after joining BJP, Kiran Bedi today said that in Prime Minister Narendra Modi the party has with it the "world's most beautiful face" as she rebutted AAP's claim that she was brought in by the saffron outfit because it does not have a face of its own in Delhi.
