Though the tenure of the current 224-member Karnataka Assembly expires on June 3, the elections are likely to be held by April-end in a phased manner, sources said.
The announcement will come after a meeting of top election officials with Union Home Secretary R K Singh today on the availability of security forces for the smooth conduct of polls in the southern state.
Chief Election Commissioner V S Sampath and Election Commissioners H S Brahma and S N A Zaidi have also held meetings with the Home Secretary along and other officials.
Karnataka is currently ruled by BJP which is struggling ever since former Chief Minister B S Yeddyurappa left the party and formed his own outfit.
