"In 2004, Congress got majority, but Sonia Gandhi did not become the Prime Minister. Is this not a betrayal?" Singh said at a campaign rally at Kathlal in Kheda district.
"Manmohan Singh's (former) media advisor Sanjaya Baru has written a book called 'Accidental Prime Minister'. Manmohan Singh is an accidental Prime Minister. He (Baru) has categorically written that the Centre was not being run by Prime Minister, but it was being run from 10 Janpath (Sonia Gandhi's residence)," Singh said.
"Sonia is super PM who is running this government." The BJP chief also took a dig at Sonia Gandhi's son-in-law Robert Vadra, saying "we have witnessed many corruption scams.... 2G, 3G, CWG and Jijaji (borther-in-law)".
"When somebody asked Pandit (Jawaharlal) Nehru if India will ever become strong, he replied that we are engaged in 'rashtra-nirman' (nation-building). Even today we are seeing advertisements of Bharat-Nirman by Congress. How long will this Bharat-Nirman continue?" Singh asked.
"There was a time when Indira Gandhi used to say that Jan Sangh (predecessor of BJP) was trying to oust her when she was trying to oust poverty. Indiraji wanted to remove poverty, but to the date poverty hasn't been removed."
He also alleged that Congress had not fulfilled any promise it made.
