The TMC, the CPI and the AAP on Tuesday announced they will skip the inauguration ceremony of the new Parliament building on May 28 and more opposition parties including the Congress are likely to join them.

Amid demands from the opposition that the president should inaugurate the new building, leaders of like-minded opposition parties deliberated on the issue and a joint statement by the floor leaders on a united boycott of the event may be issued soon, sources said.

Announcing the party's decision, TMC's leader in Rajya Sabha Derek O'Brien wrote on Twitter, "Parliament is not just a new building; it is an establishment with old traditions, values, precedents and rules — it is the foundation of Indian democracy. Prime Minister Modi doesn't get that. For him, Sunday's inauguration of the new building is all about I, ME, MYSELF. So count us out." CPI general secretary D Raja also said his party will not attend the ceremony.

Aam Aadmi Party MP Sanjay Singh tweeted, "Not inviting President Droupadi Murmu to the inauguration of the new Parliament building is a great insult to her. This is also an insult to the tribals. The Aam Aadmi party will boycott the inauguration function in protest of Modi ji not inviting the President."

The CPI-M also accused Modi of "bypassing" the President for not just laying the foundation stone for the new parliament building but also by inaugurating it himself

"Modi bypassed the President when the foundation stone for the new Parliament building was laid. Now too at the inauguration. Unacceptable. Constitution Art 79: 'There shall be a Parliament for the Union which shall consist of the President and two Houses… "Only when the President of India summons the Parliament can it meet. The President begins, annually, Parliamentary functioning by addressing the joint session. The first business Parliament transacts each year is the 'Motion of Thanks' to President's Address," party general secretary Sitaram Yechury said in a tweet.
