"He may say whatever he wants to, but why I should take his comments seriously, when his own party does not," Ravi Shankar Prasad, the party's deputy leader in Rajya Sabha, said.
Taking a jibe at Singh, Prasad said that he was speaking out of frustration as opinion polls have shown Modi as the leading contender for the prime minister's chair while Congress Vice-President Rahul Gandhi figured nowhere near him.
"People want Modi, they love him. He (Singh) may say whatever he wants to," Prasad said. Singh in a tweet had said, "BJP succumbs to threats of RSS and Ramdev and declare Modi as BJP's PM candidate. Do we still call RSS as a Cultural Organisation?" He said Modi had ditched all leaders, including LK Advani, who once supported him.
