Who was the ‘greatest politician?’

Srila Prabhupada once told us that Chanakya Pandit said politicians are not to be trusted. And yet he said that Chanakya was an expert politician and even quoted his Sanskrit slokas (Chanakya was not even a Vaisnava) in public. He once said this of him: “That is the opinion of the greatest politician in the history of the world, Chanakya Pandit.” (7 July 1973, London lecture on Bhagavad-gita, 1.1.)
