Hitting out at Congress leader Rahul Gandhi, Prime Minister Narendra Modi today said the "prince" of the Opposition party's "royal family" has declared that the country will be on fire if the BJP returns to power. "They ruled the country for 60 years, but after just 10 years out of power, they are talking about setting the country on fire," the Prime Minister said in a BJP rally at Uttarakhand's Rudrapur. He was responding to Mr Gandhi's remarks at the joint Opposition rally in Delhi's Ramlila Maidan, where he said, "If the BJP wins and then changes the Constitution, the whole country will be on fire. Mark my words, this country won't survive."
