Manmohan Singh was sworn in as India's prime minister for the second time in New Delhi today.
Having served since 2004, Mr Singh was joined by 19 others who were administered the oath of office for posts as Cabinet ministers.
The re-elected prime minister vowed to "bear true faith and allegiance to the constitution" and promised to "uphold the sovereignty of India" at the Rashtrapati Bhawan, president Pratibha Patil's official residence.
Among the most prominent appointments were MPs who will either continue holding ministries from the previous term or be handed new portfolios. Pranab Mukherjee, who was the External Affairs minister in his previous term, is touted to hold the Finance Ministry this term.
His post as External Affairs minister may go to S M Krishna, a former chief minister of the state of Karnataka. The Fulbright scholar is one of the new faces to the cabinet along with Trinamool Congress leader Mamata Banerjee.
Other ministers who were sworn in today include Sharad Pawar, A K Antony, P Chidambaram, Sushil Kumar Shinde, Ghulam Nabi Azad, and Jaipal Reddy.
With the election votes swinging largely in favour of the Congress Party, they are currently in a position to dictate terms over the appointment of Cabinet berths.
The party had a fall-out with pre-poll ally Dravida Munnetra Kazhagam (DMK) earlier today who were reportedly not satisfied with the terms. DMK leader M Karunanidhi wanted cabinet berths for his son, daughter and grand nephew besides others, which the Congress was not comfortable with.
Mr Singh is yet to announce the Cabinet berths for the newly-appointed ministers and has only said: "You will come to know in due course of time."
The Congress-led United Progressive Alliance (UPA) won 262 of the required 272 seats to form the government when results of the month-long elections were declared on May 16.
The leading Opposition Bharatiya Janata Party-led National Democratic Alliance won only 157 of the total 543 parliamentary seats.
