UK stocks continued to record gains this afternoon as sterling fell on a poll showing a narrower lead for the ruling party less than two weeks before a general election. London's FTSE index had gained 30 points (0.4%) to stand at 7,548 by 3pm.

Tokyo's Nikkei index fell 126 points (0.6%) to finish at 19,687 as energy shares took a hit following an OPEC decision not to deepen output cuts seen as crucial for boosting oil prices. The Hang Seng index in Hong Kong inched eight points (0.03%) higher to close at 25,639 as last night's record close on Wall Street was offset by losses in energy firms.
