Prime Minister Atal Bihari Vajpayee will face his first no-confidence motion on Monday, but there is no serious threat because the National Democratic Alliance government that he leads has a decisive majority in the Lok Sabha.

Even the Dravida Munnetra Kazhagam, which was upset at the Bharatiya Janata Party's attempts to rope in the 11-member All India Anna Dravida Munnetra Kazhagam, has said it will support the government. The AIADMK will meet on Monday to take a decision.

• The No-confidence Motion: The Complete Coverage

The debate on the motion, which will be initiated by Leader of the Opposition Sonia Gandhi at noon, comes against the backdrop of the controversy over the Public Accounts Committee report on defence procurements for the Kargil War. The opposition has repeatedly accused Vajpayee of being insensitive to its sentiments and demanded clarifications on issues ranging from Defence Minister George Fernandes's re-induction into the Cabinet to the PAC issue.

It will be the 26th no-confidence motion in the Lok Sabha's history.

Barring one, which remained inconclusive, all the no-trust motions in the past were failed.

A record 15 such motions were moved against governments led by Indira Gandhi, mother-in-law of Sonia Gandhi.

There were three each against the governments headed by Lal Bahadur Shastri and P V Narasimha Rao.

Interestingly, Vajpayee had brought one of the motions against Indira Gandhi in March 1967. He also moved a no-confidence motion against Rao.

The only non-Congress government against which no-confidence motions were brought twice was led by Morarji Desai, who headed the Janata Party regime.

One of these, brought by Congress leader Y B Chavan in July 1979, led to the resignation of the prime minister even before it could be voted upon.

Vajpayee and now his deputy, Lal Kishenchand Advani, were ministers in the Desai government.

The first no-confidence motion in the history of the Lok Sabha was moved by socialist Acharya Kriplani against Jawahar Lal Nehru in August of 1963.

The last was against the Narasimha Rao government in July 1993, moved by Ajay Mukhopadhyay of the Communist Party of India. It was a close shave for Rao. He survived by just 14 votes.

Of the 25 such motions so far, only four were negatived by a voice vote, while the rest were decided by a division of vote.

In around ten confidence motions moved in the House, the Vajpayee government faced one and fell by one vote in April 1999. His 13-day government also fell in 1996, but he had then announced his decision to resign and the confidence motion was not put to vote.
