Modi once again slammed Samajwadi Party leader Naresh Agarwal's comments that a tea vendor cannot become the prime minister.
"UPA members are saying a tea vendor cannot become the prime minister. It is for the people to decide if a tea vendor will become the prime minister or not, but it is still better than a person who sells the country," he said.
