European shares dipped on Tuesday as concerns that growth will be hit by high oil prices offset better-than-expected earnings updates from companies including Alcatel and L'Oreal. Crude prices held around $59 a barrel as markets eyed another developing tropical storm in the Atlantic with the potential to disrupt production and refining, just as oil companies were assessing the damage caused by Hurricane Dennis in the Gulf of Mexico, Reuters reported. Shares in BP fell 0.8 percent after the oil major reported its Thunder Horse platform in the Gulf was listing by an estimated 20 to 30 degrees after the passing of Dennis. Traders said any delays to getting the platform running could affect BP's oil production next year. By 1035 GMT, the FTSEurofirst 300 index of pan-European blue chips was 0.3 percent weaker at 1,154.6 points, just a handful of points below the three-year high it hit before last week's bomb attacks in London. The narrower DJ Euro Stoxx 50 index eased 0.2 percent to 3,240.5 points, having climbed from a year low of 2,944 points in late April. --More 2224 Local Time 1924 GMT
