NEW DELHI: BJP chief Amit Shah – the architect of the party’s thumping victory that enabled it to come to power at the Centre for a second term – became the most prominent new entrant in the government of Prime Minister Narendra Modi in its second stint.Shah, 54, took oath Thursday after days of speculation whether he would become part of the government. A section in the BJP wanted him to stay on as the party chief as assembly polls in a string of states come up later this year, and elections in Delhi and Bihar the next.

BJP leader J P Nadda has emerged as the likely replacement for Amit Shah as the party president after he was left out of the Union Council of Ministers according to BJP sources. Nadda, a Brahmin leader from Himachal Pradesh, enjoys the confidence of the party’s top brass, is trusted by the Rashtriya Swayamsewak Sangh – the party’s ideological parent- and enjoys a clean reputation.
