The Congress today termed as unconstitutional the continuation of the Karnataka Chief Minister B S Yeddyurappa, allegedly involved in the allotment of land to his family members. Talking to reporters in New Delhi, Party spokesperson, Jayanthi Natarajan said, her party strongly condemns the continued functioning of Yeddyurappa as the Chief Minister, even after accepting his own illegal act. She said the national leadership of the BJP stands exposed for its double standards.Replying to a question on her party's debacle in the Bihar Assembly elections, Mrs. Natarajan said Congress will introspect on the causes for the poor show.
