Madhav Singh Solanki is a leader of Indian National Congress party and a former External Affairs minister of India. He was the four times chief minister of Gujarat. He is known for KHAM theory by which he came to power in Gujarat in 1980.
In 1981, the Government of Gujarat headed by the chief minister Solanki, introduced the reservation for socially and economically backward classes based on recommendations of Bakshi Commission. It resulted in anti-reservation agitation across the state which spilled over in riots resulting in more than hundred deaths. Solanki resigned in 1985 but later returned to power winning 149 out of 182 assembly seats. He was supported by Kshatriya, Harijan, Adivasi and Muslims; called collectively as KHAM formula. It resulted in other communities losing the political influence.
