"That is why we said we will speak on Bihar Day only after others reveal their stand," the Sena chief said in an apparent reference to the MNS.
Praising Kumar for his work, the Sena patriarch said, "Due to the fabulous leadership Bihar has got in the form of Nitish Kumar, the state, a backward region engulfed in casteism, is on the road to development."
Speaking on the issue of Marathi pride, he said no one was more aggressive than Shiv Sena in opposing "atrocities" on Marathi-speakers in Belgaum by the Kannada people. "Shiv Sena's fist is firm and Mumbai will remain for Marathi-speakers," he said.
