The swearing-in ceremony is expected to be a grand affair as it marks the Bharatiya Janata Party's return to power in Delhi after 26 years.
According to reports, the Chief Ministers of all NDA-ruled states will be invited for the same.
Meanwhile, Union Home Minister Amit Shah is likely to meet BJP president JP Nadda on Sunday to discuss the government formation in the national capital.
Delhi BJP chief Virendra Sachdeva will meet the 48 newly elected MLAs this evening.
As per NDTV's sources, PM Modi, Amit Shah, and JP Nadda have already discussed the government formation and oath ceremony at the BJP headquarters last evening.
While the BJP leadership is yet to announce its choice for the Chief Minister's post, newly elected New Delhi MLA Parvesh Verma is being seen as the frontrunner after he defeated Aam Aadmi Party (AAP) national convener Arvind Kejriwal.
A former two-time MP from West Delhi, Verma was denied a parliamentary election ticket last year.
He took on Kejriwal in a seat he had won thrice in a row and defeated him by 4,000 votes. He is the son of former Delhi Chief Minister, late Sahib Singh Verma.
The BJP won 48 seats in the 70-member Assembly and the incumbent AAP finished at 22.
