NDTV has accessed a document which is Cambridge Analytcia's pitch to the Congress, a document where the firm, which gained notoriety after illegally accessing personal data of Facebook users, promised that it would transform the Congress ahead of the 2019 elections.

On Trending @ 10, we ask: how would this company, with this murky past, have operated to get data so significant that it could influence India's political landscape?
