Besides, party treasurer Piyush Goel and two spokespersons Prakash Javadekar and Nirmala Sitharaman have joined the government.
Shah, along with general secretary J P Nadda and BJP's Gujarat unit in-charge Om Prakash Mathur, are in the race for the party president's post, it is learnt.
BJP will also see new faces in the party as it does not want to weaken the organisation ahead of crucial Assembly polls in Maharashtra and Haryana later this year and Jammu and Kashmir and Jharkhand early next year.
BJP's ideological fountainhead, the RSS, also wants that the organisation should remain vibrant and strong unlike in 1999 when the party had become debilitated as all bigwigs went into the government and the party lost touch with the grassroots.
