FTSE 100 gets boost after weak dollar helps commodities

By Alistair Smout LONDON (Reuters) - FTSE 100 rallied on Thursday, rebounding from the previous session's falls after a drop in the dollar boosted commodity prices and gave a lift to mining and oil shares. Britain's FTSE 100 rose 36.50 points, or 0.6 percent, to 5,873.64 by 0926 GMT, set to snap a three-day losing streak that had seen the index shed 4 percent. The rally in oil prices came even after data showed the oil market remained oversupplied.
