The Tata Sons board on Thursday backed two critical resolutions—paving the way for a fresh five-year extension for Chairman N Chandrasekaran and greenlighting a proposal for the holding company's public listing, sources told NDTV Profit. However, the sweeping moves face an immediate roadblock. Sources reveal that Noel Tata, who holds veto rights on the board on behalf of Tata Trusts, disagreed with both proposals and has invoked his veto power to block the resolutions.
