Turkey’s economy is almost one-third bigger than previous estimates, boosting the government’s per capita income targets and increasing the prospect its credit rating will be raised.

According to official figures released on Saturday, Turkey’s gross domestic product was TL758bn ($606bn, £300bn) in 2006, a 31.6 per cent rise on the previous estimate of TL576bn. Per capita income for that year was raised sharply, from $5,480 to nearly $7,500.
