Shiv Sena, however, sought to clear the confusion over Uddhav Thackeray's participation, saying since the event was only for the MPs belonging to the Centre's ruling alliance, their leader will not go.
"I will attend it and so will all Sena MPs," Shiv Sena's lone member in the Narendra Modi government Anant Geete told PTI.
He said it is not as if leaders of other NDA constituents have been invited and Uddhav left out.
"It is not as if (Punjab Chief Minister and Shiromani Akali Dal leader) Parkash Singh Badal has been invited and Uddhavji hasn't. Since (Union Food Minister and Lok Janshakti Party leader) Ram Vilas Paswan is a Member of Parliament, he has been invited for the event. Even our MPs have been invited and they will attend the event," he said.
"If Uddhavji wants to meet PM Modi, he will directly go and meet him alone. Why should he need a dinner invite to meet him?" the Sena leader said.
Meanwhile, Athawale said Uddhav is "very keen" on his party forming a coalition government with BJP and that there is "no doubt now" about the alliance being revived.
