Exane BNP Paribas lifted its rating for the Anglo-Dutch publishing group to “outperform” from “underperform” on valuation grounds.<br /><br /><strong>Home Retail Group </strong>was also hoisted by broker comment, adding 2.7 per cent as Barclays Capital started coverage on the Argos-owner with an “overweight” rating in an otherwise negative initiation note on the European retail sector.<br /><br />Banks were the biggest drag on the blue-chip index, with <strong>Royal Bank of Scotland</strong> the top faller, off 8.2 per cent.

Lloyds shares fell 6.2 per cent, while <strong>Barclays</strong>, <strong>HSBC</strong> and <strong>Standard</strong> <strong>Chartered</strong> shed 0.8 to 3.6 per cent.<br /><br />Miners were weak reflecting easier metal prices as doubts about the demand outlook resurfaced. <strong>Vedanta</strong> <strong>Resources</strong>, <strong>Fresnillo</strong>, <strong>Rio</strong> <strong>Tinto</strong>, <strong>Xstrata</strong>, <strong>Anglo</strong> <strong>American</strong> and <strong>Kazakhmys</strong> lost 2.1 to 5.1 per cent.
