In January 1977, Indira Gandhi dissolved the Lok Sabha and declared that elections to the body were to be held during March 1977. Opposition leaders were also released and promptly formed the Janata alliance to fight the elections. The alliance registered a landslide victory in the election. On the urging of Jayaprakash Narayan, the Janata alliance selected Desai as their parliamentary leader and thus the Prime Minister. Morarji Desai became the first non-Congress Prime Minister of India. The Desai administration established tribunals to investigate Emergency-era abuses, and Indira and Sanjay Gandhi were arrested after a report from the Shah Commission. In 1979, the coalition crumbled and Charan Singh formed an interim government. The Janata Party had become intensely unpopular due to its internecine warfare, and a perceived lack of leadership on solving India's serious economic and social problems.
