Amid demands from the opposition that the president and not the prime minister should inaugurate the new Parliament building, the leaders of several political parties have decided to boycott the ceremony on May 28.
Sources said the leaders of like-minded opposition parties deliberated on the issue and a joint statement by all the floor leaders will be issued soon, announcing a united boycott of the event.
Meanwhile, the Trinamool Congress (TMC) and the Communist Party of India (CPI) and the Aam Aadmi Party (AAP) said they will skip the inauguration.
The sources added that the final decision will be taken on Wednesday, once the formal invitation is received by the parties.
