Kumar and Modi are likely to leave late tonight for Gandhinagar, where the ceremony will take place tomorrow, in presence of Prime Minister Narendra Modi and BJP president Amit Shah, besides chief ministers of other NDA-ruled states.
The Bihar CM had rejoined the NDA a few months ago, four years after having snapped ties with the BJP.
He had predicted a comfortable victory for the saffron party in the home state of the Prime Minister, who served as Gujarat chief minister for three terms.
The party has decided to reappoint Vijay Rupani and Nitin Patel as the state's chief minister and deputy chief minister, respectively.
