The contest is between a "a decisive government and an indecisive past", Modi said in his address to a rally in this western Uttar Pradesh town a day after announcing that India had demonstrated anti-satellite missile capability by shooting down a live satellite.
On the one side there is a strong 'chowkidar', on the other, a line of tainted people, the prime minister said.
"India has made up its mind who to vote for," he told the rally.
"I will give an account of my work, but at the same time seek an account from my opponents... a 'chowkidar' does no injustice," he said.
Modi began his speech by paying tribute to Choudhary Charan Singh, former prime minister and father of RLD leader Ajit Singh who has aligned with the BSP and the SP in this election.
Taking a jibe at people seeking proof of Air Strikes by Indian Air Force in Balakot, PM said “We need saboot or sapoot?, My nation’s sons are the proof of airstrikes; those who are seeking proof are challenging the sons of the nation”.
PM further spoke on DRDO’s satellite launch and said “Our scientists were demanding for testing of shooting down of satellite in space, their government (UPA) postponed this decision also. To make the India of 21st century strong and for its security, this decision should have been taken long ago. But it kept getting delayed”.
