New Delhi, Aug 29 (ANI): Politicos on Friday gave mixed reactions on senior Congress leader Janardan Dwivedi's remark that politicians should not remain in active posts beyond an age. Dwivedi earlier in the day said a generation change is necessary in politics and politicians should quit by 65-70. The senior Congress leader's comment came just days after the BJP dropped former Prime Minister Atal Bihari Vajpayee and party veterans Lal Krishna Advani and Murli Manohar Joshi from its Parliamentary Board.
