In an interview to NDTV Profit, Digvijaya Singh offered damning praise of Dr Manmohan Singh - the Congress General Secretary said the PM is doing a "fairly good job". In the same interview, he hints that his substantial criticism of Home Minister P Chidambaram , expressed a few months ago, has had a positive effect. Mr Singh had last year described the Home Minister as arrogant and inflexible in the context of his handling of the Naxal crisis. He says that since then, the Home Minister "has changed a lot".
