In a reference to Prasad's recent statement in the wake of MNS leader Raj Thackeray's anti-North Indian stir that he would come to Mumbai to perform Chhat pooja,'Thackeray, in an editorial published in party mouthpiece Saamana said, the Karunanidhi government has issued an ordinance making Tamil compulsory in all schools in the state.

"Lalu who has turned Bihar into a hell, should hold a mela of Biharis in Tamil Nadu ruled by his ally at the Centre to champion the cause of North Indians there."

Launching a scathing attack on the reported demand by some local North Indian Congress leaders that Hindi be made an official language in BMC, Thackeray said, "let them try this out in Chennai, Bangalore, Hyderabad, Kolkota and Guwahati first."

"The sons of soil here will not tolerate any insult to the status of Marathi and Mumbai," the edit added.

Thackeray said Congress leaders making the demand to impose Hindi on Mumbai's civic body should be prosecuted by the Maharashtra government and put behind bars.
