New Delhi, Aug 13 - State-run power utility NTPC Ltd has been legally advised by the government to move the Supreme Court to secure gas from Mukesh Ambani-led Reliance Industries at the price agreed to with it earlier.

The top two law officers of the government, Attorney General Goolam E. Vahanvati and Solicitor General Gopal Subramaniam, have advised NTPC to move the apex court at once to secure its own interest in the gas row between the two Ambani brothers.

'NTPC should take all possible steps to protect its interest as advised by the solicitor general,' said Vahanvati, endorsing the solicitor general's legal opinion to the government.

Though the attorney general refused to comment on the issue, saying 'the mater is subjudice,' a top law ministry official said the unanimous opinion by the two law officers has already been forwarded to NTPC.
