A Diwali greeting has snowballed into a political controversy, triggering a fresh clash between the Congress and the BJP. The row erupted after Congress chief Mallikarjun Kharge referred to Diwali as 'Khushiyon Ki Eid', drawing sharp criticism from BJP leaders, who questioned the comparison and accused the opposition party of indulging in appeasement politics. The Congress has defended the sentiment behind the remark, setting the stage for yet another political battle over religion, language and symbolism.
