The Cabinet Committee on Economic Affairs, CCEA on Wednesday referred the Cairn-Vedanta deal on energy to a Group of Ministers, GoM. Petroleum Minister S Jaipal Reddy said after the meeting in New Delhi that the GoM will be headed by Finance Minister Pranab Mukherjee. On Tuesday, the UK-based Vedanta Group had said it has received market regulator Sebi's nod to acquire a 51 per cent stake in Cairn India and will launch an open offer soon. Cairn India, which holds 70 per cent stake in the 6.5 billion barrels Rajasthan block, does not pay any royalty and is opposed to making it cost recoverable as it will dent its profits. ONGC holds the remaining 30 per cent stake in the block. Earlier, ONGC said that royalty, like any other levy, is cost recoverable and cited provisions in the field contracts to assert its point.
