BJP vice-president Prabhat Jha today attacked ruling Congress and Prime Minister Manmohan Singh calling him the "weakest PM" of the country. Jha was referring to the book 'The Accidental Prime Minister: The Making and Unmaking of Manmohan Singh' written by Sanjaya Baru, former media advisor to Manmohan Singh.

"Because of Congress president Sonia Gandhi and vice-president Rahul Gandhi, the condition of Prime Minister Manmohan Singh looks like a prisoner, which has resulted in lowering the country's credibility," Jha said here while addressing a rally.

Calling Manmohan Singh "submissive", the BJP leader said, "10-Janpath (Sonia Gandhi's residence), had not agreed to even a single decision made by Singh and he became the country's weakest prime minister."
