Noel Tata has sought a discussion and vote on merging Tata Electronics and Tata Consulting Engineers with Tata Sons to help it retain its private status.
The proposal comes after the RBI rejected Tata Sons' application for deregistration and maintained its listing requirement.
In a separate letter, Noel has sought details on the Shapoorji Pallonji Group's proposal to partially exit its Tata Sons stake to raise ₹25,000 crore.
