* The FTSE 100 closed down 25.36 points, or 0.4 percent, at 5,868.16, on Tuesday led lower by miners and banks, the stars of the recent rally fueled by the U.S. Federal Reserve's third round of quantitative easing and the ECB's bond buying plan.

* There is little in the way of economic data for investors to chew on with just the minutes from the recent Bank of England monetary policy meeting due out at 0830 GMT.

* The Bank of Japan eased monetary policy on Wednesday by boosting asset purchases by double the usual amount, as slowing global demand and mounting tensions with China have hurt chances of a near-term recovery in the export-reliant economy.

* Copper prices were little changed on Wednesday, with a U.S. stimulus-led rally wearing off as worries over Spain's debt resurface and traders reported fading interest from top consumer China with prices not far from 4-1/2-month highs.

* BP : The energy firm has been in talks to sell its 400,780 barrel-per-day Texas City, Texas, refinery to Marathon Petroleum Corp MPC.N, according to a report posted by the Financial Times on its website on Tuesday.

BP shut a Norwegian oil and gas field after a potentially dangerous leak, the company said on Tuesday, six days after the incident forced the emergency shutdown of the facility.

* UNITED UTILITIES : The utility firm rose on Tuesday amid talk that a Middle East sovereign wealth fund might be willing to pay up to 950 pence-per-share for the firm, according to media reports.

* JJB SPORTS : JD Sports Fashion has ruled itself out of a rescue bid for JJB Sports, its floundering rival, according to newspaper reports.

* Aviva, G4S and Petrofac will go ex-dividend on Wednesday, after which investors will no longer qualify for the latest dividend payout.
