Shiv Sena MPs are also attending the function. MPs will be given ministerial presentations on Prime Minister's Swachh Bharat Abhiyan, Saansad Adarsh Gram Yojana and Jan Dhan Yojana.
It is the first interaction of the Prime Minister with the NDA MPs since the government took office.
It comes at a time when Mr Modi is riding high on BJP's electoral success in Maharashtra and Haryana assembly elections.
