China's Central Bank Cuts Interest Rates to Halt Share Falls

China's central bank has cut interest rates by 0.25% in an attempt to halt a dramatic slide in share prices and boost the wider economy. The main index in Shanghai closed down more than 7.5% on Tuesday. That followed yesterday's "Black Monday" when prices dropped by 8.5%, Shanghai's biggest one-day fall since 2007. Also on the programme, South Africa's economy shrinks and profits at mining giant, BHP Billiton, dive in the face of China's declining demand for commodities.
