What's common between TMC and AIADMK MPs? Both MPs never mention their leaders names without a salutation.

So, TMC's Sultan Ahmed inadvertently caused much laughter in Parliament when he spoke about the West Bengal CM calling her Didi Mamata Banerjee. 

Congress benches commented that it was the Amma syndrome -- which is that an AIADMK MP always opens his speech with a salutation to the former TN chief minister, calling her Amma Jayalalitha..

Ahmed, refused to take the taunt lying down and said Congress MPs do much of the same to Priyanka Vadra.
