Holding the Footsie back, however, are a couple of mining heavyweights. ENRC ( LON:ENRC ) is in the dog-house on reports in the Financial Times (FT) yesterday that the Serious Fraud Office has asked the law firm Dechert to provide it with some documents. Dechert was investigating corporate governance issues at ENRC prior to being fired by the Kazakh miner a few weeks ago, the FT reports. Major ENRC stake-holder Kazakhmys ( LON:KAZ ) is dragged down with ENRC. The FTSE 100 is up 27 (0.43%) to 6,271.
