In the 1990s, many parties Bahujan Samaj Party (BSP), the Samajwadi Party and the Janata Dal started claiming that they were representing the backward castes. Many such parties, relying primarily on Backward Classes' support, often in alliance with Dalits and Muslims, rose to power in Indian states. At the same time, many Dalit leaders and intellectuals started realising that the main Dalit oppressors were the so-called Other Backward Classes, and formed their own parties, such as the Indian Justice Party. The Congress (I) in Maharashtra long relied on OBCs' backing for its political success. Bharatiya Janata Party has also showcased its Dalit and OBC leaders to prove that it is not an upper-caste party. Bangaru Laxman, the former BJP president (2001–2002) was a former Dalit. Sanyasin Uma Bharati, former CM of Madhya Pradesh, who belongs to OBC caste, was a former BJP leader. In 2006 Arjun Singh cabinet minister for MHRD of the United Progressive Alliance (UPA) government was accused of playing caste politics when he introduced reservations for OBCs in educational institutions all around.
