Kenya will take at least 21 months to take back full control of Kenya Airways, buying out minority shareholders and converting shares held by banks into Treasury bonds, a lawmaker briefed on the transaction said. The loss-making airline, which is 48.9% govt-owned and 7.8% held by Air France-KLM, was privatised 23 years ago but sank into debt and losses in 2014. Lawmakers voted to re-nationalise it this week. "The (transport) ministry needs 3 months to think through and then give us a proposal on the aviation shareholding company and the entire structure," David Pkosing, the chairman of parliament's transport committee, said. He estimated buying out shareholders would take 18 months. Air-France KLM will have the option of selling its stake to the govt and staying on as a technical partner for the airline. <br/>
