The mood in the Shiv Sena soured after MNS chief Raj Thackeray last Sunday announced support for Modi without joining either the NDA or the five-party saffron "Grand Alliance" in the state.
He also announced the putting up of MNS candidates against Shiv Sena nominees except in Pune.
Uddhav spoke out his mind this afternoon when he charged his estranged cousin Raj of attempting to garner votes by capitalising on Modi's name.
"They are deliberately trying to mislead the people by extending support to Modi ... But, the Marathi votes are with Shiv Sena," Uddhav remarked.
Targeting ally BJP at a media conference, he demanded to know "whether they are following the path of Aam Aadmi Party chief Arvind Kejriwal?"
