European stocks closed higher on Friday with sentiment boosted by better-than-expected growth data from the euro zone, while Italian shares reacted positively to the prospect of a new prime minister.
Euro zone GDP beats
The pan-European provisionally closed higher by 0.5 percent at 1,331.59 points.
Data released mid-morning showed the euro zone economy grew faster than expected in the fourth quarter of 2013. Official figures published by Europe's statistics agency, Eurostat, revealed the economy had expanded by 0.3 percent compared with the previous quarter, above analyst forecasts of 0.2 percent.
This came after early-morning figures showed the German and French economies grew at a similar pace in the final quarter of 2013, bridging the gap seen in recent quarters between the euro zone's two largest economies, as investment picked up in both regions.
France's economy grew 0.3 percent in the final quarter of 2013, slightly more than the 0.2 percent analysts had expected, after seeing no growth in the third quarter. Germany, meanwhile, grew 0.4 percent in the quarter, a faster growth rate than the 0.3 percent growth consensus.
