The pan-European FTSEurofirst 300 closed provisionally 0.9 percent lower at 1,340.3 points, The U.K.'s FTSE 100 and the French CAC 40 both unofficially ended down 1 percent, while the German DAX was 0.8 percent lower.

This came after Markit's final euro zone Purchasing Managers' Index (PMI) showed manufacturing expanded a little less than forecast last month. The reading came in at 50.6, just below initial estimates of 50.7. Any figure over 50 indicates expansion.
