Just in: Digvijaya Singh tells the Congress party that he is ready to take on Narendra Modi in Varanasi. Singh on Friday asked the party's youth brigade to launch a strong, fearless and "tit-for-tat" campaign against Modi on social media. "I have not seen a person who is more of a coward and a bigger liar than Modi. If you fear countering this liar, you should go and sit at home. If anybody from the BJP opposes us, he should be replied to in the same language that they use against us. Be fearless and write whatever you want against Modi. He who fears does not live. They have a paid team of professionals and we are volunteers. Counter their propaganda everywhere you can," Singh had said while addressing a national convention of the National Student's Union of India.
