On Thursday, Apr 12 Thackeray had dared Nitish to celebrate Bihar Divas on Apr 15. While addressing a rally at Idgah maidan, Raj said, "I thought that Nitish Kumar was a nice person who was developing his state. Nitish said, 'I don't need visa to come to Mumbai'. Reacting to Nitish's comment, Raj said, "let us see how he (Nitish) celebrates Bihar Din in Mumbai."
Raj had asked the necessity of celebrating Bihar Divas in Mumbai as Biharis are spread all over the nation. He wanted Maharashtra Chief Minister Prithviraj Chavan and Deputy Chief Minister Ajit Pawar to ask Nitish not to celebrate the divas in Mumbai.
