Vajpayee's 13-day tenure as PM shortest in Indian history
Late Prime Minister Atal Bihari Vajpayee's first tenure as an elected PM lasted 13 days, which is the shortest in Indian history. He took oath as the PM in May 1996, and resigned 13 days after forming the government, amid a no-confidence motion. He was re-elected in 1998, but lost a no-confidence motion by a single vote 13 months later.
