Emerging as the nation's single largest party in the April/May 2004 Lok Sabha election, Congress currently leads a coalition government under Prime Minister Manmohan Singh. Party President Sonia Gandhi was re-elected by the Party National Executive in May 2005. Also a Member of Parliament, she heads the Congress Lok Sabha delegation. Congress prides itself as a secular, left of center party, with a long history of political dominance. Although its performance in national elections had steadily declined during the last 12 years, its surprise victory in 2004 was a result of recruiting strong allies into the UPA, the anti-incumbency factor among voters, and its courtship of India's many poor, rural and Muslim voters. Congress political fortunes suffered badly in the 1990s, as many traditional supporters were lost to emerging regional and caste-based parties, such as the Bahujan Samaj Party and the Samajwadi Party, but have rebounded since its May 2004 ascension to power. It currently rules either directly or in coalition with its allies in 9 states. In November 2005, the Congress regained the Chief Ministership of Jammu and Kashmir state, under a power-sharing agreement.
The Bharatiya Janata Party (BJP), led by Rajnath Singh, holds the second-largest number of seats in the Lok Sabha. Former Prime Minister Atal Bihari Vajpayee serves as Chairman of the BJP Parliamentary Party, and former Deputy Prime Minister L.K. Advani is Leader of the Opposition. The Hindu-nationalist BJP draws its political strength mainly from the "Hindi Belt" in the northern and western regions of India.
The party holds power in the states of Gujarat, Madhya Pradesh, Rajasthan, Chhattisgarh, and Orissa—in coalition with the Biju Janata Dal. Popularly viewed as the party of the northern upper caste and trading communities, the BJP made strong inroads into lower castes in recent national and state assembly elections. The party must balance the competing interests of Hindu nationalists, (who advocate construction of a temple on a disputed site in Ayodhya, and other primarily religious issues), and center-right modernizers who see the BJP as a party of economic and political reform.
Four Communist and Marxist parties are united in a bloc called the "Left Front," which controls 57 parliamentary seats. The Left Front rules the states of West Bengal and Kerala. Although it has not joined the government, Left Front support provides the crucial seats necessary for the UPA to retain power in New Delhi; without its support, the UPA government would fall. It advocates a secular and Communist ideology and opposes many aspects of economic liberalization and globalization, resulting in dissonance with Prime Minister Singh's liberal economic approach.
