Prime Minister Narendra Modi has inaugurated India’s new parliament building amid protests and boycotts.
Most opposition parties did not participate, saying they wanted the president instead of Mr Modi to open the building.
During the ceremony, some of India’s top wrestlers detained when they tried to reach the new parliament to protest.
The new building has replaced the British-era parliament.
Ceremonies leading up to a formal inauguration began at 07:00 (02:00 GMT) on Sunday.
Mr Modi unveiled a plaque dedicating the building to the nation and later addressed a gathering of lawmakers.
They criticised the government for not asking President Droupadi Murmu, 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 a divisive figure, while the ruling Bharatiya Janata Party (BJP) hails him as a hero.
The new parliament building is part of the government’s ambitious project to develop the Central Vista complex in Delhi to replace colonial-era government 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) – is much bigger and has the capacity to seat 1,272 MPs.
The Lok Sabha chamber, will seat the lower house of the parliament, has 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.
The current parliament building will converted into a museum.
