Congress MLC Ravi on Wednesday said that both Siddaramaiah and DK Shivakumar are eligible and fit for the post of Karnataka chief minister. "Shivakumar fought very strongly when the party was going through a tough phase. Siddaramaiah is one of the tallest and highly experienced leaders of Karnataka. Both the leaders are eligible for the Karnataka CM post. The high command is most likely to take the final call today," he said.
