D. P. Yadav

Dharam Pal Yadav is an Indian gang leader from Western Uttar Pradesh who later joined politics. He is often referred to with epithets such as "mafia don", "underground don" or the "unrivalled don of western Uttar Pradesh". He is the father of Vikas Yadav, the convicted murderer of Nitish Katara. He was a MLA (member of the state legislature) four times (three times from Bulandshahr and once from Sahaswan) and also a MP (member of parliament) twice (representing Sambhal in both the Rajya Sabha and Lok Sabha). His wife, Umlesh Yadav, was MLA from Bisauli. His nephew is currently Member of Legislative Council (MLC) from Badayun.

Yadav joined a liquor bootlegging gang in the 1970s and quickly racked up nine murder charges. One of his bootlegged liquor ventures allegedly killed 350 people in the early 1990s. Seeking security from prosecution, he was inspired by the leader of his gang to join politics. Yadav befriended Mulayam Singh Yadav and Vichitra Veer Yadav and J.P. Yadav represented the Samajwadi Party, winning state elections in 1989, and was also on Mulayam's cabinet of ministers. There was no progress in most of the criminal cases against him. In 2004, he became a member of the Indian Parliament under the Bharatiya Janata Party but such was the ensuing scandal that the party threw him out within days.

In 2007, he formed the party Rashtriya Parivartan Dal, and two members were elected to the state legislature — himself from Sahaswan, and his wife Umlesh Yadav from Bisauli. Thereafter, he joined Mayawati's Bahujan Samaj Party and ran in the Indian General Election of 2009, but he lost. He left BSP just before the Assembly Elections in 2012, sensing a tide against BSP. He wanted to join the Samajwadi Party but was snubbed due to his criminal activities. He ran in the election as a candidate of his own party but lost.
