ISTANBUL (Reuters) - Turkey’s economy is expected to record double-digit growth in 2021, President Tayyip Erdogan said on Thursday, higher than a previous government forecast of 9%. “Even though international institutions say 9%, we think that we will reach double-digit growth numbers at the end of the year,” Erdogan said in a pre-recorded message. Turkey’s economy grew 21.7% year-on-year in the second quarter. Reporting by Ezgi Erkoyun and Ali Kucukgocmen; Editing by Toby Chopra
