Bharatiya Janata Party on Tuesday made a strong demand for a parliamentary probe into the multi-crore Satyam Computer Services [Get Quote] scam, saying it would unravel the truth behind the scandal that shook corporate India.

Raising the issue in the Rajya Sabha, Leader of the Opposition Jaswant Singh made a demand for a probe by a House Committee into the Rs 7,800 crore (Rs 78 billion) fraud.

"Only such a probe can bring out the truth," he said adding that the inquiry should be conducted within a specific time-frame. Singh made the demand during the Zero Hour after corporate affairs minister Prem Chand Gupta evaded pleas for constitution of a Joint Parliamentary Committee made earlier during the Question Hour.

Gupta said CBI has been ordered to probe the scam in Satyam Computers, whose founder B Ramalinga Raju had confessed to account manipulation in the country's premier IT firm.
