The Congress on Monday stepped up its campaign for the dismissal of the H D Kumaraswamy government in Karnataka, stating that it has been reduced to a minority.

All India Congress Committee General Secretary Prithviraj Chavan, who had an hour-long meeting with Governor Rameshwar Thakur on Monday morning, later told reporters that the party had demanded that the Kumaraswamy government be dismissed immediately in the wake of its coalition partner Bharatiya Janata Party withdrawing support.

"The Kumaraswamy government cannot remain in office as it has been reduced to a minority," Chavan said.

In a related development, a delegation of Congress leaders, headed by senior leader Dharam Singh, called on the Governor for the second time since Sunday and demanded the imposition of President's rule and the dismissal of the present minority government.

Congress MLAs submitted individual letters to the Governor, stating that they will not support any government other than the one formed by the party. The decision to hand over resignation letters to Thakur was taken at a meeting between Chavan and his party leaders on Sunday night, sources in the Congress said.
