Indian Prime Minister Narendra Modi has inaugurated new parliament building amid a boycott of the ceremony by 20 opposition parties.
Ceremonies leading up to a formal inauguration began at 7:00 local time (02:00 GMT) on Sunday, reports BBC.
Modi also installed a historically significant gold sceptre called the sengol in the parliament.
He unveiled a plaque dedicating the building to the nation and is expected to make a speech later in the day.
Last week, 20 parties - including the main opposition Congress - announced their "collective decision" to boycott the inauguration ceremony.
They criticised the government for not asking President Droupadi Murmu, who is head of state, to open the new building. They also denounced the decision to hold the event on the birth anniversary of Hindu nationalist ideologue VD Savarkar.
Opposition parties consider Savarkar as a divisive figure, while the ruling Bharatiya Janata Party (BJP) hails him as a hero.
The BJP has called the boycott a "disrespect of democracy".
The new parliament building is part of the government's ambitious project to develop the Central Vista complex in capital Delhi which replaces colonial-era buildings.
Built in front of the old parliament, the new four-storey building - built at an estimated cost of 9.7bn rupees ($117.1m, £94.2m) - has increased seating capacity.
The Lok Sabha chamber, which will seat the lower house of the parliament, is designed in the likeness of a peacock, India's national bird. The Rajya Sabha chamber, which will seat the upper house, is designed to resemble the lotus, India's national flower.
