Janata Party president Subramanian Swamy demanded on Friday that Prime Minister Manmohan Singh give sanction to prosecute telecom minister A Raja under Prevention of Corruption Act, following Central Bureau of Investigation searches in telecom ministry to probe allegations of a multi-crore spectrum scam.

"The raids by CBI on a first information report registered (against unknown DoT officials ) at the Sanchar Bhavan under PCA now makes the granting of sanction by the Prime Minister a formality under the Act," he said in Chennai.

Swamy recalled that he had filed a petition to the prime minister in November last year seeking the sanction to launch criminal investigation on a private complaint under different sections of the PCA.
