Naresh Agrawal, a powerful Samajwadi Party leader once known to be close to party chief Akhilesh Yadav, joined the BJP today in Delhi with a controversial remark that forced his new party to issue a disclaimer. "Shri Naresh Agarwal has joined Bhartiya Janata Party. He is welcome. However, his comments regarding Jaya Bachhan ji are improper and unacceptable," Ms Swaraj has tweeted.
