Italy has fallen into its third recession in a decade as a slump in domestic demand caused the economy to shrink.
GDP fell by 0.2 per cent in the final three months of last year, following a 0.1 per cent decline in the third quarter. The usual definition of a recession is two consecutive quarters of contraction.
The eurozone as a whole expanded by 0.2 per cent, the same pace as in the previous quarter.
Compared with the final quarter of 2017, eurozone GDP rose by 1.2 per cent, its weakest 12-month performance since the 2012-13 recession that accompanied the sovereign debt crisis.
"This was a disappointing end to the year," said Andrew Kenningham at Capital Economics, who noted that surveys of businesses taken in December and January had recorded falling growth, meaning "the prospects for the first quarter of this year currently look no better".
