Mumbai Congress leader Sanjay Nirupam has asked the 74-year-old Bollywood superstar to stop promoting GST or face protest from the party. Sanjay Nirupam said ,"He should not promote GST in its current form. There is already anger among traders against it. There will be protests against it and also against Big B as he is the brand ambassador. So he should not promote GST".The superstar responded by saying he is doing it because he was asked.A 40-second video featuring Bachchan has also been released by the government, in which the actor explains GST as a "unifying force, just like the three colours in the national flag".
