The major trends in the electoral performance of BJP since 1989 can be traced as follows:
i. In the elections of 1989, the National front under V.P. Singh came to power supported by left front and BJP from outside because they wanted to keep the Congress out of power. Due to Mandal Commission Report and implementation of its recommendations. National Front forced BJP to reconsider its support and BJP finally withdrew it. Thus, in 1990, the rule of National Front came to an end.
ii. In 1996, BJP minority government was formed for a short period. In June 1996, BJP failed to get majority support in the vote of confidence and thus collapsed.
iii. From March 1998 to October 1999, BJP and others formed alliances, NDA, under the leadership of Atal Bihari Vajpayee. The regional Parties demanded more share in the government to extend their support.
