Europe's main stock markets rose slightly on Friday as traders digested mixed retail sales data out of Britain and looked ahead to a meeting of the world's 20 major economies. London's benchmark FTSE 100 index climbed 0.22 percent to stand at 6,828.11 points in midday deals. Frankfurt's DAX 30 inched up 0.02 percent to 9,620.49 points and in Paris the CAC 40 climbed 0.24 percent to 4,365.95 compared with Thursday's closing levels. "The main focus of the European session has been driven by the UK, where the release of the retail sales figure drew increased attention," said analyst Joshua Mahony at Alpari traders. "Retail sales have always been key as a determinant of where the economy is going given that it reflects both current and future expectations for the everyday person from an employment, wage growth and inflation standpoint." British retail sales slid by 1.5 percent in January after spiking by 2.5 percent a month earlier, official data showed on Friday. They jumped by 4.3 percent in January compared with the same month in 2013, the Office for National Statistics said. Retail sales had spiked in December as shoppers spent heavily ahead of Christmas. "The Christmas period will have given a boost to December’s numbers, while January had to cope with poor weather and the traditional post-Christmas time of domestic austerity," said Chris Beauchamp, an analyst at IG trading group. "Nonetheless, the picture looks better for the UK economy at the moment, with growth still looking reasonable and weaker inflation helping to make life easier for consumers."
