"It's only a matter of 100 days, Congress' exit is confirmed. They won't survive," the BJP prime ministerial said at an public rally here.
Launching a scathing attack on Singh, Modi said even if an ordinary worker from Assam would have represented the state for so many years, he could have changed the face of the state but Singh failed to do so and owed an explanation to the people for it.
"For 23 years you have been sending Prime Ministers from here. You tell me, you made such a big investment but what did you get in return. Did you get anything...If he being yours could not do anything for you, then what will he do for the nation," he asked the people while addressing a public meeting here.
"Among all Northeast states, Assam's condition is the worst," he said, alleging "Congress leaders are narrow minded. Their thinking is narrow, dreams are small and vision is shortsighted."
He said, "Prime Minister ji if even a small worker from Assam would have sat in Rajya Sabha for 23 years, he would changed the face of Assam. You are sitting in Rajya Sabha for 23 years, holding the coveted post of Prime Minister and yet your own state of Assam is facing such a bad condition, then you can imagine in what bad shape will the whole country be."
Modi said in a democracy people of Assam and that of the nation have the right to demand an explanation from the Prime Minister for failing to meet their expectations.
"Prime Minister ji, you will have to reply. People of the country have the right to seek an answer from you and people of Assam have a special right to demand an answer from you," the Gujarat Cjhief minister said while addressing the 'Mahajagaran Samawesh', Modi's first rally in Guwahati.
He focussed on attacking the Congress governments, both at Assam and the Centre.
"You have tolerated Congress for 60 years. They only made promises and misguided the country. Give me just 60 months, I will fulfil your aspirations," Modi said.
Attacking Congress government over corruption, the BJP leader said "They are depositing black money abroad and do not want to bring it back."
The BJP government will do everything to bring all black money to India and invest in various development works, including for the poor, spreading education and giving food and medicine to the elderly, he said.
