Stock indices traded lower on the uncertainty over the Greek debt talks and on the weaker-than-expected industrial production data from the Eurozone. The International Monetary Fund (IMF) spokesman Gerry Rice said on Thursday that the IMF's technical team has left the debt talks in Brussels. The reason is "major differences", he noted. "There are major differences between us in most key areas," Rice said.

News reported that Germany was preparing for a Greek default.

The Office for National Statistics (ONS) released its construction output data for the U.K. on Friday. Construction output in the U.K. declined 0.8% in April, after a 1.4% rise in March.
