"My son Manavendra Singh won the Barmer Lok Sabha constituency in 2004 on a BJP ticket by a margin of over two lakh (200,000) votes. Where is the caste equation here?"
Singh said it was the highest margin ever from Barmer-Jaisalmer. "If caste equation had dominated this constituency, such a victory would not have been possible for my son."
Singh claimed he enjoyed a popular support base across caste and communities in Barmer. "I have three lakh (300,000) Muslims supporting me but I am not a Muslim," he said.
Singh, who has also been leader of opposition in the Rajya Sabha and chairman of the important Public Accounts Committee of Parliament which oversees government spending, said it was an "absolutely facile and incorrect explanation" by the BJP which has maintained caste equations do not favour Singh's candidature.
Singh appeared confident he would win the election.
