The party made the demand in a memorandum submitted to President Pratibha Patil in New Delhi today, a release of the Punjab Pradesh Congress Committee (PPCC) said here.
"It is with a deep sense of anguish that we would like to draw your kind attention towards total subversion of democracy and law and order in the state," the memorandum said.
The party accused the SAD-BJP alliance government with having "unleashed a reign of terror and repression on activists and leaders of the Congress" since the time it assumed power in March 2007.
False cases were registered and many of them were illegally detained and brutally tortured by the Punjab Police at the instance of the SAD-BJP leaders, the Congress alleged.
The opposition Congress also charged the SAD-BJP alliance with having indulged in booth capturing and intimidation of voters during various elections, including Municipal Corporation, Block Samiti and Zila Parishad held in the state.
