Samajwadi Party (SP; literally, Socialist Party; founded October 4, 1992) is a recognised state political party in India based in the Indian state of Uttar Pradesh (UP). It describes itself as a democratic socialist party and is mainly representing the interests of a caste grouping called Other Backward Classes (OBCs).
The Samajwadi Party was one of several parties that emerged when the Janata Dal (People's League), fragmented into several regional parties. The Samajwadi Party is led by Mulayam Singh Yadav, who was Chief Minister of Uttar Pradesh and defence minister of India.
The Samajwadi Party is primarily based in Uttar Pradesh. Its support is largely based on OBCs (Other Backward Castes), particularly Mulayam Singh Yadav's own Yadav caste, and Muslims. It has contested Lok Sabha and State Assembly elections around the country, though its successes have been mainly in Uttar Pradesh. In the assembly election in Madhya Pradesh in 2003, the Samajwadi Party gained 7 seats, making it the third largest party in the state. When its candidate won the by-election of Lanji (Balaghat) in 2007, its total tally reached 8.
In the 15th Lok Sabha, it currently has 22 members, making it the third largest party in that house.
In the 2007 Uttar Pradesh legislative election, the SP won only 96 seats as compared to 146 in the previous election. As a result, Chief Minister Mulayam Singh Yadav had to resign, with his rival Mayawati, leader of the BSP (which won a majority of 207 seats), sworn in as the Chief Minister.
In the 2012 legislative assembly elections of Uttar Pradesh, SP registered a landslide victory with a clear majority in the House, thus enabling it to form the Government in the state. This was expected to be the fifth term of Mulayam Singh Yadav as Chief Minister of state, but he surprised everyone by selecting his son, Akhilesh Yadav, to be the new chief minister (the youngest ever). It became official on March 15. It was also the first time that SP was head of the UP government for a full term of 5 years.
Position in state and national politics
The Samajawadi Party has been providing outside support to the United Progressive Alliance government. However, it contested the 2009 general election in alliance with the Rashtriya Janata Dal and the Lok Janshakti Party of Bihar.
The Samajwadi Party(S.P) still supports the central UPA Government from outside at the national level. It is currently the third-largest party in parliament. In general elections in 2009, it won 23 seats, behind the Indian National Congress with 206 seats and the Bharatiya Janata Party with 116 seats.
