Andhra Pradesh CM Chandrababu Naidu on Monday called PM Narendra Modi a 'vindictive' leader with whom even BJP's ally Shiv Sena is unhappy. "Uddhav Thackeray is best friend of mine...Bal Thackeray was very affectionate towards me," he added. "I took the principal stand to protect democracy...[But] if there's no democracy...[no one] will be able to talk anything," he further said.
