Solution

Following are the main trends in the BJP's election performance from 1989:
1. The Left Front and the BJP supported the National Front under V.P. Singh in the 1989 elections because they wanted to keep the Congress out of power. The Mandal Commission Report and its recommendations' implementation led the BJP to reevaluate its support, which it ultimately abandoned. As a result, the National Front's reign came to an end in November 1990.
2. A temporary BJP minority government was established in 1996. The BJP fell in June 1996 after failing to win a majority of the vote in a vote of confidence.
3. Under the direction of Atal Bihari Vajpayee, the BJP and other parties formed the NDA (National Democratic Alliance) between March 1998 and October 1999. To increase their level of support, the regional Parties requested a larger part of the government.
4. The political rivalry in the 1990s, which was split between the Congress- and BJP-led coalitions.
