With the Congress' victory in Karnataka all but a formality pending the announcement of results, the question of "who will be chief minister" is now the hot topic of debate. And staking his claim already for the top post is senior party leader K Siddaramaiah. "I am one of the strong contenders," said the five-time MLA from Varuna in south Karnataka. But the leader, hailing from the Kuruba community, a backward caste, also added that the final call rests with the party high command.
