Prime Minister Narendra Modi will open a 10-hour parliamentary debate marking the 150th anniversary of Vande Mataram, amid controversy over his remarks about Congress altering the song in 1937.
The NDA government has been allotted three hours to speak in the Lok Sabha before the discussion moves to the Rajya Sabha.
Eight Congress leaders, including Gaurav Gogoi and Priyanka Gandhi Vadra, will participate in the debate, setting the stage for a politically charged session.
