Hindu nationalist Bharatiya Janata Party leader Narendra Modi will be sworn in as India's 15th prime Minister on 26 May.
The swearing-in ceremony, which will be presided over by President Pranab Mukherjee, will take place at Rashtrapati Bhavan, or the presidential palace, in New Delhi, at 6pm IST (1.30pm BST).
Along with the new prime minister, the new ministers will also take oath of office.
The Bharatiya Janata Party (BJP) won a historic majority in the 2014 Indian general election, and Modi, under whom the party fought the elections, has promised a leaner cabinet of ministers.
"Tomorrow, will begin the day by visiting Raj Ghat & paying my respects to Pujya Bapu [Gandhi]. Overwhelmed by greetings from friends across India & the world. I am deeply grateful for your continuous support & best wishes," 63-year-old Modi wrote on Facebook ahead of the swearing-in ceremony.
The oath-taking ceremony of Modi will be attended by the heads of state of neighbouring countries, including Pakistan, Sri Lanka and Nepal, as well as by the leaders from other SAARC countries.
"Great having leaders from SAARC nations & Mauritius join us during the ceremony. Their presence will make the occasion more memorable," Modi said.
He also appreciated the decision of Pakistan and Sri Lanka to release Indian fishermen held in those countries.
"I welcome the step by Sri Lanka & Pakistan to release our fishermen. I welcome our fishermen brothers back home!"
The event will also see a host of celebrity guests that include veteran actors Amitabh Bachchan, Rajnikanth and Anupam Kher, among others.
