BRUSSELS (Reuters) - The euro zone economy grew more strongly than expected in the second quarter as the bloc rebounded from a recession caused by the COVID-19 pandemic, preliminary data showed on Friday. The European Union’s statistics office Eurostat said gross domestic product in the 19 countries sharing the euro grew 2.0% quarter-on-quarter for a 13.7% year-on-year increase. Economists polled by Reuters had expected a 1.5% quarterly and a 13.2% annual increase.
