I get the feeling Yakub may be following orders from someone else- in a dramatic twist, it could be Vikrant. While most of the characters are portrayed as relatively normal in Indian politics, and Aditya, as a real hero, unlike Rahul Gandhi (who is a subject of jokes on the internet), if this was supposed to be the Nehru-Gandhi family, they've somehow either exposed or smeared muck all over Vadra. Either he's part of the plan, or he'll end up dead, bringing relief to viewers- the latter likely, since he is not a very relevant character in the plot.
It's not entirely a reference to the Nehru-Gandhis. The real Nehru-Gandhi family were referenced when the show mentioned the assassinations of Indira and Rajiv. Besides, we don't hear of Maneka Gandhi pushing for her son Varun to be the Prime Minister of India. I feel, just to distract viewers, they'll stuff in parts of Narendra Modi in Aditya Singhania.
