New Delhi, May 13 (IANS): Congress leader Digvijaya Singh Monday launched an indirect attack on the judiciary for calling the Central Bureau of Investigation a "caged parrot".

The Congress leader said such comments "belittle" national institutions.

"CBI is a parrot in a cage, a bench calls IB (Intelligence Bureau) a chicken... Now, I have put a question to the people in general - are we not belittling our institutions?" the Congress general secretary asked reporters.

The Supreme Court dubbed the CBI a "caged parrot" last week, while making observations after the investigation agency submitted an affidavit on the government's interference in its probe report on coal block allocations.

The Bangalore bench of the Central Administrative Tribunal (CAT) said Sunday that the Information Bureau (IB) was like a "chicken", while hearing a petition from a woman Indian Police Service officer who sought revocation of the move to send her back to her original cadre, ending her deputation to the IB.

When reporters asked Digvijaya Singh for his reaction to the analogy between institutions and fowl, he said: "I will also request you to get access to all those who are calling institutions chicken or parrot, you should get reaction from them as well."
