"They (BJP) were with us when they needed us and left us when the need was fulfilled. What did they do with Bishnoi? They said in a public rally that he would be the next Haryana chief minister. I have the tape recording to prove it," he told reporters after casting his vote in suburban Bandra.
"Why did they stab us in the back? BJP will have to answer that," he said.
The Sena leader, however, maintained he personally respected Modi, who had been frequently targeted by party mouthpiece 'Saamana' and its Hindi publication after the split between the two saffron allies.
"I have not insulted Narendrabhai. I have respect for him," Uddhav said while responding to criticism by senior BJP leaders of an article published by 'Dopahar Ka Saamana' slamming Modi which also had a derogatory reference to his father.
"BJP will not tolerate insult to the Prime Minister. We are not a helpless party. It is unfortunate that Shiv Sena is unnecessarily raking up Modi's family background to garner sympathy," Union Minister Nitin Gadkari told reporters in Nagpur after casting his vote.
State BJP President Devendra Fadanvis too criticised remarks against Modi and said the people of Maharashtra will give a befitting reply to the Shiv Sena in today's poll.
"It is improper for the Sena to touch this low...it is against Maharashtra' culture. We have a tradition of respecting our elders," he said.
The 'Dopahar Ka Saamana' had on Tuesday poured vitriol on Modi, saying he and his party had forgotten Sena's contribution to their landslide victory in the Lok Sabha elections.
However, Uddhav had distanced himself from the article in the newspaper.
