Congress leader Digvijay Singh yesterday took potshots at the Comptroller and Auditor General (CAG) for his “valuable advice” on providing constitutional backing for the CBI and the CVC and wondered why he was not taking steps to “stop leaks of reports” from his office.

He was addressing reporters a day after CAG Vinod Rai said the Central Bureau of Investigation and the Central Vigilance Commission should be given constitutional backing to enable them to function independently.
