Samajwadi Party (SP) nominated Jaya Bachchan as its candidate for Rajya Sabha polls and bypassed Naresh Agarwal as the candidate. On twitter, Swaraj welcomed Agarwal into BJP, however, said that his remarks on Jaya Bachchan were "improper" and "unacceptable".
Yadav also urged the Women Commission to take cognizance in this matter.
With 14 candidates, from Union Finance Minister Arun Jaitley and other bigwigs to an independent, entering the fray for ten vacant Rajya Sabha seats from Uttar Pradesh, a contest to the Parliament's Upper House became imminent on Monday.
Agarwal, a two-time Rajya Sabha MP and seven-time MLA, is not new to controversial remarks. Pandit Sukhram Sharma, Narayan Rane, Mukul Rai, BS Yeddyurappa and Naresh Agrawal, all great leaders.
Agarwal's decline within the SP started after he organised a party at a Delhi five-star hotel in July past year.
With 324 MLAs of the BJP-led National Democratic Alliance, and 37 needed to win one seat, the party can secure eight Rajya Sabha seats from the state, with 28 votes to spare.
Senior BJP leader and Foreign Minister Sushma Swaraj tweeted: "Naresh Agrawal has joined BJP".
On Monday, Agrawal said: "I am joining the BJP as I think that until you are in a national party, you can not do anything for the society".
Agarwal said, "My ticket was denied for a person who dances in films. The RLD MLA from Chaprauli may also shift to the BJP camp", a BJP leader said.
Agarwal, who has courted controversies with his statements in the past as well, made the remarkson Monday in the presence of BJP leaders, including Union minister Piyush Goyal, at a press conference held at the party headquarters.
