The euro zone economy grew at the same quarterly rate in the fourth quarter as in the third, data showed on Tuesday, defying expectations of an acceleration.
The European Union's statistics office Eurostat said gross domestic product in the 16 countries using the euro at the time grew 0.3 percent in the October-December period, the same as in the third quarter.
Year-on-year, the expansion was 2.0 percent in the fourth quarter, compared to 1.9 percent in the third quarter.
Economists polled by Reuters had on average expected increases of 0.4 percent quarter-on-quarter and of 2.1 percent year-on-year.
