Prafulla Kumar Mahanta

AGP candidates secured a notable victory in December 1985, Mahanta who was one of those people, became the Chief Minister, he became the youngest person in the country to hold such a high office. His first administration, however, was beset by allegations of corruption and problems of escalating violence linked to the United Liberation Front of Assam (a militant separatist group in the state). In 1990 the authorities in New Delhi dismissed the AGP government and took direct rule of the state. A split in the party in 1991 and voter dissatisfaction with its performance in its first administration led to a poor performance for the party in the 1991 assembly elections.

Following an AGP resurgence in the 1996 state assembly elections, Mahanta became the chief minister for a second time. That tenure became highly controversial, especially after the revelation of a counterinsurgency strategy that allegedly was under the direction of Mahanta. In June 1997 the ULFA staged an attack on Mahanta, after which the police coerced ULFA cadres who had surrendered to the authorities to kill family members of active insurgents. An official commission that later was to investigate the killings and it concluded in 2007 that Mahanta was directly responsible for the policy. Also during his second administration, Mahanta was alleged to have been involved in a corruption scandal involving fraudulent letters of credit and avoided prosecution only through the intervention of the governor of Assam. Investigation of the matter was reopened in 2010. The 2001 elections were terrible for the AGP as they only won 20 seats. On top of that, it was alleged that Mahanta had had an extramarital affair, he subsequently was ousted as president.

Despite the allegations of secret killings he organized against families of ULFA members, documented in the report by the Saikia Commission to the Assam Assembly, Mahanta was missed from political leadership in the state. He was reinducted into the AGP after the AGP (Progressive) was dissolved during the presidency of Chandra Mohan Patowary, and regained a prominent position in the party.

In a 2010 interview on NDTV's Walk the Talk with Shekhar Gupta, editor-in-chief of The Indian Express, Mahanta said:

"For the sake of the integrity and security of India, we are ready to take any blame. If the insurgent groups attack our forces, then they (the security forces) must have the right to respond. However, the charge against me on extra judicial killings of the ULFA sympathisers is to malign my image."[8]

In the same interview, he said that unknown agencies of the Congress Party had conspired in massacres during the Assam Movement in the early eighties.

Aside from the current chief minister of the state, Mahanta is regarded as the most powerful and influential politician of Assam.
