In an interview to Zee News, Singh said that Manmohan Singh never had the courage to stand up to Sonia Gandhi. In his book One Life is Not Enough, he said that files from the Prime Minister's Office (PMO) were passed onto Sonia Gandhi.
He even alleged that Sonia had turned down the PM post after immense pressure from Rahul Gandhi. Rahul, he alleged, dissuaded Sonia from taking the PM post fearing that she would too be assassinated like his father.
He even said that though Rahul Gandhi is a good man, he lacked the fire for politics saying that it was a 24*7 job.
Singh has even blamed Manmohan Singh for the failures of UPA-II.
