Agra: Lashing out at the "adulterated" politics of the opposition and corruption of the Congress, BJP President Amit Shah and UP Chief Minister Yogi Adityanath on Sunday urged voters to back Prime Minister Narendra Modi-led NDA for better governance and national security.

Scoffing at the opposition alliance's politics, which he said, was without principles and policies, Shah, addressing a rally at the Agra College grounds, joked that of they came to power, each day of the week could have a new Prime Minister.
