London rose 0.2 percent in late morning deals, while Paris gained 0.1 percent and Frankfurt fell 0.1 percent in early afternoon trade.

Eurozone economic growth hit 0.4 percent in the January-March period from 0.7 percent in the previous quarter, the EU's Eurostat statistics agency confirmed in its latest estimate, but analysts laid the blame on temporary factors.
