Congress chief Rahul Gandhi's statement that Prime Minister Narendra Modi does not give adequate respect to his "mentor" and party veteran LK Advani has generated a huge political controversy. In a further jibe, Mr Gandhi said he was the first to pay a visit to former Prime Minister Atal Bihari Vajpayee, who is undergoing treatment at a Delhi hospital. The BJP furiously hit out, accusing Mr Gandhi of practicing the "lowest form of politics".
