"This year, the 1989 batch will be celebrating its silver jubilee. We have sent a formal invitation. We are hopeful he would be coming to meet his batch mates arriving from across the country and even abroad," said Aditi Sharma, general secretary, Students' Alumni Cell.
Besides the 1989 batch, the institute is also hosting the golden jubilee and ruby jubilee of different batches, with over 250 IITians expected to attend.
The West Bengal unit of the Aam Aadmi Party (AAP), which has undertaken a membership drive across the state is also hoping to cash in on Kejriwal's visit and planning to organize a mass meeting in the city.
"The membership drive is in full swing and it will really get a big boost with Kejriwal's presence. Although he is yet to confirm his presence, we are working on organizing a mass meeting in the city, to be addressed by him," AAP volunteer Jaswant Singh said.
He said party volunteers were in talks with several well-known names from various fields in the state for joining the party with an eye on the coming Lok Sabha elections.
AAP will be organizing a seminar in Rishra of Hooghly district on Sunday to spread awareness about the party and to boost its membership.
