The Congress Party, along with 19 other opposition parties, boycotted the inauguration of the new Parliament building on 10 June 2023. The parties cited a number of reasons for their boycott, including:

• The fact that Prime Minister Narendra Modi inaugurated the building instead of President Droupadi Murmu, who is the head of state. The opposition parties argued that the President, as the highest constitutional authority, should have been the one to inaugurate the building.
• The fact that the government did not invite the opposition to the inauguration ceremony. The opposition parties felt that this was a snub and that it showed that the government was not interested in working with them.

• The fact that the government has not been transparent about the cost of the new Parliament building. The opposition parties have alleged that the government has spent a lot of money on the building, and that this money could have been better spent on other things, such as healthcare or education.

The government has defended its decision to inaugurate the new Parliament building without the opposition. The government has said that the President was not available on the day of the inauguration, and that it invited the opposition to the ceremony but they did not respond. The government has also said that it has been transparent about the cost of the new Parliament building, and that the money has been spent on a state-of-the-art building that will be a symbol of India's democracy.

The boycott of the inauguration of the new Parliament building is a sign of the growing political divide in India. The opposition parties are increasingly unhappy with the government, and they are using this boycott as a way to register their protest. The government, for its part, is not backing down, and it is showing that it is willing to take on the opposition. It remains to be seen how this political divide will play out in the future.
