Investor confidence was hit by news that recession in the 17-nation eurozone deepened sharply in the final three months of 2012 as the debt crisis continued to sap growth.
The eurozone economy shrank 0.6 percent in the three months to December, which compared with a contraction of 0.1 percent in the previous quarter, according to official data.
