(FILES) In this file photo taken on May 23, 2019, Indian Prime Minister Narendra Modi (L) and President of the ruling Bharatiya Janata Party (BJP) Amit Shah gesture as they celebrate the victory in India's general elections, in New Delhi. - As the battle-hardened drill sergeant for Prime Minister Narendra Modi, Amit Shah has long been considered India's second most-powerful person and his appointment on May 31 as home minister elevates his position to leader-in-waiting. While Modi is the right-wing Bharatiya Janata Party's people person firing up rallies and mastering Twitter, the BJP president has for years made sure that Modi's orders are carried out to the letter while turning the world's biggest political party into the undisputed force across the nation of 1.3 billion people.
