NEW DELHI: Calling Congress “synonymous with confusion and conspiracy”, BJP claimed on Tuesday that the party had compromised national security as the erstwhile Sonia Gandhi-led National Advisory Council was a “supporting ground for Naxalites” during the UPA regime and some party leaders “romanticised” Naxalism.“Congress tried to mainstream Maoism and Naxalism during its rule and the party should therefore call itself Congress Party of Maoists or Indian National Congress (Maoists),” BJP spokesman Sambit Patra said at a presser.He showed a letter which he said was written by one “comrade” to another and it talked about Congress willing to fund their activities and contacting its leader Digvijaya Singh for assistance.He alleged the letter contained a phone number of Digvijaya Singh, who he said was Congress president “Rahul Gandhi’s guru”.The controversy also spilled over into poll-bound Madhya Pradesh, with CM Shivraj Singh Chouhan urging Congress to expel Singh, and Digvijaya hitting back by daring the government to arrest him.
