Tamilnadu BJP chief Annamali has alleged that State Minister Udhayanidhi Stalin lacks maturity and is making irresponsible remarks against Governor RN Ravi. Taking part in a meeting held in Tirunelveli, Annamalai said, ‘Governor is constitutionally selected. Will Udhayanidhi relinquish his post and take Group 4 exams.’ Nothing can be done in NEET issue now. There are some practical difficulties. However students in Tamilnadu have been doing well in clearing NEET exams, he added. DMK is doing politics with NEET. They are confused now. Their hunger strike on Sunday drew lukewarm response from people, he added.
