Prime Minister Narendra Modi is expected to reply to the two-day debate on the Constitution in the Lok Sabha on Saturday, Parliament sources said.
Defence Minister Rajnath Singh is likely to initiate the debate on the Constitution, among the key demands of the opposition alliance for the Winter Session of Parliament.
Home Minister Amit Shah is expected to initiate the debate in the Rajya Sabha on Monday and PM Modi will reply to it on Tuesday.
Winter Session of the Parliament, which is scheduled to end on December 20, has been marked by clashes between the ruling party and the Opposition, with each accusing the other of distracting voters.
The Congress has slammed the BJP for claiming links between ex-party chief Sonia Gandhi and businessman George Soros, while the Bharatiya Janata Party has been criticised over issues like the farmers' protests.
Opposition parties had sought discussions in both Houses to mark the 75th anniversary of the adoption of the Constitution.
The Opposition has also been targeting the ruling BJP over claims the third Modi government will look to alter the Constitution on fundamental level.
These claims were among the major campaign issues raised by the Congress and other parties ahead of the 2024 Lok Sabha polls. Leader of Opposition Rahul Gandhi and MP Priyanka Gandhi Vadra have frequently waved the red-bound copy of the Constitution at speeches to make their points.
Both also took oaths as MP with a copy in their hands.
