Slovenia's market-leading mass grocery retailer Mercator has announced that it will enter Bulgaria by launching two outlets by the end of 2009. The move ties in with the retailer's wider strategy to invest in promising Central and Eastern European (CEE) markets that have attracted less investment from Western Europe's biggest retailers than some of the region's higher profile markets. Through to 2013, BMI has forecast MGR sales in Bulgaria to increase by 49% and reach US$2.34bn, which is an upbeat appraisal that will encourage Mercator.
