According to reports, Tamil Nadu Chief Minister J Jayalalithaa will also attend the ceremony.
Among the other CMs likely to be present in the function is Parkash Singh Badal of Punjab. Senior BJP leaders L K Advani, Arun Jaitley and Sushma Swaraj will also be present.
Sources said that Shiv Sena leader Udhav Thackeray has been invited for the oath taking function.
They said the JD(U), which is ruling Bihar in coalition with the BJP, may not have any representative at the ceremony owing to its Chief Minister Nitish Kumarís known disagreement over possible projection of Modi as BJPís prime ministerial candidate for the 2014 Lok Sabha elections.
The ceremony is expected to be attended by hundreds of BJP workers, among others, from across the state.
Caste factor may play a role in formation of new cabinet
Community representation is likely to figure prominently in the new Gujarat cabinet at a time when the pitch for a bigger role for Narendra Modi in the BJP is rising following his third consecutive thumping victory in the state elections.
The swearing-in ceremony on December 26 will be followed by formation of a new cabinet.
While the new cabinet is not likely to sport a surprisingly new look considering that Modi had repeated all of his ministers in the elections, the defeat of three cabinet and five state ministers may pave the way for induction of a few new faces.
According to sources, the new cabinet is likely to be bigger than the previous one which had 30 ministers. They said Modi may accommodate more MLAs this time to avoid any discontent among his leaders and keeping the caste representation in mind.
While old faces like Anandi Patel, Vaju Vala, Nitin Patel, Saurabh Patel, Vasan Ahir, Mangu Patel, Ramanlal Vora and Pradipsinh Jadeja are likely to remain part of the cabinet, veterans like Bhupendrasinh Chudasma, Ranchod Rabari, Dilip Thakor, Vasuben Trivedi and Babu Bokhiria may also get ministerial berths this time.
Thirty-nine Patel leaders, including Leuva and Kadva, have won this time. And with Leuva heavyweight Dileep Sanghani and Dalit leader Fakir Vaghela, both cabinet ministers, losing this election, the cabinet is expected to see a few new entrants to balance the caste equation.
The group of 11 newly-elected women MLAs is a mixed bag with Anandi Patel leading them. There are other experienced leaders like Nima Acharya, Bhanu Babariya and Vibhavari Dave, and first-timers like Poonam Madam, Nirmala Wadhwani and Sangita Patil.
