The Telangana unit of the CPM has decided not to compete in the Munugodu Assembly constituency by-election.
It has instead decided to enter into an alliance with another political party.
State secretary of the party Thammineni Veerabhadram said that the party would ally with that other party with the best ability to defeat the right-wing BJP in the constituency.
Thus, the CPM would declare its support to either the TRS or the Congress after an evaluation of their chances for victory in the constituency, he said.
He said that the party would take a decision on the issue in a week.
The Left parties have won the seat five times in the past, and so the key political parties of the State are now eagerly waiting for the announcement of the CPM.
