Mr.Atal Bihari Vajpayeev Vs Number 13

Name: Atal Bihari Vajpayee Birth Date: 25 December 1924 Birthplace: Gwalior, MP Occupation: Prime Minister Born In: Madhya Pradesh

*)  April 13, Prime Minister Atal Bihari Vajpayee will leave for Lucknow to file his nomination papers. 

*)  The date was chosen because 13 is a lucky number for him.

*)  He was sworn in on a 13th and successfully led the 13th Lok Sabha.

*)  That he was able to remain in the saddle for 13 days even when he did not enjoy majority support is also cited in this context.

*)  Since the counting of votes is, again, on a 13th (May), the BJP believes nothing will prevent Vajpayee from returning to South Block.
