BJP President Amit Shah on Monday called Andhra Pradesh CM Chandrababu Naidu a "U-turn chief minister". "When Atal Bihari Vajpayee became the PM, Naidu joined the NDA, but left it in 2005 after the NDA government fell in 2004," he added. Shah further said that "all doors to the NDA are closed for Naidu. We will not take him back".
