Why is the 'Vande Mataram Bill' in focus? What punishment has been proposed for insulting the national song?

The Centre is set to introduce a significant amendment to the Prevention of Insults to National Honour Act, 1971, with the aim of extending the same legal protection to the national song 'Vande Mataram' that is currently available to the national anthem 'Jana Gana Mana'. https://ift.tt/veHCWpc
