Ageing Kazakh leader gives green light to constitutional reforms

Kazakhstan's veteran leader Nursultan Nazarbayev gave the green light on Wednesday for constitutional reforms that could dilute the sweeping powers he has amassed as president and force his eventual successor to share power with other institutions. Kazakhstan, an exporter of oil and metals, is the only former Soviet republic that is still run by its communist-era leader. Now aged 76, Nazarbayev has so far not identified a clear successor and investors fear what may come after him.
