Data released in France also showed a marked slowdown in growth at the worst of the sovereign debt crisis bite hard into demand. Europe's second-largest economy registered no growth at all for the third consecutive quarter.

"Although the pace of growth slowed compared to (the first quarter) the outcome was slightly better than expected," said Barclays' economist Thomas Harjes in a research note to clients. "However, the risk of another soft patch in H2 2012 is significant as most parts of Southern Europe remain in recession and overseas demand has also softened lately."#
