The Eleventh Kerala Legislative Assembly Council of Ministers in Oommen Chandy's first ministry, was a Kerala Council of Ministers (Kerala Cabinet), the executive wing of Kerala state government, led by Indian National Congress leader Oommen Chandy from 31 August 2004 to 12 May 2006.
This government came into office following the resignation of A.K. Antony from the Chief Minister's post ostensibly due to the debacle of the United Democratic Front in the 2004 Lok Sabha Elections.
This was the 19h Ministry in Kerala and it comprised 20 ministers.[1]
Oommen Chandy was sworn in as the Chief Minister of Kerala on 31 August 2004 after the controversial resignation of A. K. Antony on 29 August. All ministers in the previous Antony government except K.M. Mani, P.K. Kunjalikkutty, K.R. Gowri Amma, M.V. Raghavan, Dr. M.K. Muneer, Babu Divakaran and C.F. Thomas were ousted. Kunjalikkutty resigned on 31 December 2004, after finding himself guilty in the notorious Ice Cream Parlour Scandal. He was succeeded by his colleague V.K. Ibrahim Kunju the next day (1 January 2005). K.P. Viswanathan, who handled the department of Forests, resigned on 9 February 2005 after a series of scandals, and A. Sujanapal succeeded him on 4 January 2006. In the interval, the CM himself handled the department of Forests.
