Prime Minsiter Narendra Modi will celebrate his 68th birthday today in Varanasi. Modi will pay obeisance to Lord Shiva at the Kashi Vishwanath temple and later watch a film “Chalo Jeete Hain” inspired by his life along with a few school children. Meanwhile BJP President Amit Shah said that the PM’s birthday coincides with a week-long special service programme undertaken by the BJP to honour late PM Atal Bihari Vajpayee. BJP workers will observe the day as 'seva day'.
