Commenting on the book “The Accidental Prime Minister: The Making and Unmaking of Manmohan Singh” by the prime minister's former advisor Sanjay Baru, veteran BJP leader LK Advani said the book endorsed what everyone knew — that Manmohan Singh was the weakest prime minister.

“The book has officially endorsed what everyone knew... When I said I feel he (Manmohan Singh) is the weakest prime minister ever, my colleagues said he is a nice man, why do you criticise him so much,” Advani said. “I pity him, and have sympathy for him,” he added.
