Inflation in Turkey in June soared to an annual rate of 78.6 per cent -- the highest in 24 years, according to official data released Monday -- as President Recep Tayyip Erdogan's unconventional economic policies continued to take their toll.
But independent estimates published by Turkish economists showed prices rising at more than double that figure.
The inflation rate reported by Turkey's state statistics agency was the highest since the emerging market suffered a currency meltdown during a global financial crisis in 1998.

"Stop committing crimes for the benefit of President Erdogan," Kilicdaroglu told the agency on Twitter.
A survey published by the Metropol polling agency on Friday showed that 69 per cent of respondents believed the unofficial ENAG figure and just 24 per cent the one reported by the government.
Cost-of-living problem
Erodgan has doubled down on his economic approach and hinted that he may want the benchmark interest rate to move even lower in the months to come.
He has also tried to reverse the accompanying drop in his public approval by announcing a rapid series of wage hikes for large parts of the population.
