There have been two occasions when the prime minister has tabled a notice of a motion of confidence but resigned before it was moved (Charan Singh in 1979 and Vajpayee in 1996). V.P. Singh in 1989, Chandra Shekhar in 1990, Narasimha Rao in 1991 and 1993, Deve Gowda in 1996, Gujral in 1997 and Vajpayee in 1998 all won motions of confidence. V.P. Singh in 1990 and Deve Gowda in 1997 lost such motions.

What happens if both a motion for no-confidence and a motion for confidence are tabled? In 1990, when V.P. Singh had tabled a motion of confidence and a member had given notice of a no-confidence motion, the speaker had given precedence to government business and taken the motion of confidence.

What happens if the prime minister loses a motion of confidence? In such a case, he is obliged to resign, and the president should try to identify another person who enjoys the confidence of the Lok Sabha. Before the vote on the confidence motion, the prime minister may also recommend to the president that the House be dissolved; such a recommendation has to be followed. However, he cannot make such a recommendation after he loses the confidence motion.

When do governments propose motions of confidence? This is usually done in three scenarios. First, if there is doubt that the government has the support of the majority of MPs, usually after some MPs have withdrawn support — as in the current scenario. In that case, the prime minister may pro-actively seek such a vote to demonstrate that he has support and is empowered to take important strategic decisions — such as the nuclear deal. (Of course, this could be a risky strategy, as witnessed by V.P. Singh and Deve Gowda, but it pre-empts a no-confidence motion.) Second, the government may want to corner some critical MPs who may not wish to vote against it. (For example, will the Left parties vote with the BJP?) Third, it may decide to precipitate a crisis to ensure that all its allies, with possibly some divergent interests, band together.
