Aug 24 (Reuters) - London"s FTSE 100 rose on Tuesday as commodity-related gains outweighed weakness in consumer staples and pharmaceutical stocks, while easing worries about central banks tapering stimulus kept sentiment in check. After falling as much as 0.46%, the FTSE 100 index (.FTSE) ended 0.2% higher, helped by heavyweight mining stocks (.FTNMX551020) up 2.4%. Limiting the advances, however, were pharmaceutical stocks (.FTNMX201030) that weakened 1.1% to be the top losing sub-index. "Basically we have been trading waters while we look across Europe and that seems to have been the trend throughout the day," said Craig Erlam, senior market analyst at Oanda. "I think at this point all eyes are on the Jackson Hole meeting, so it wouldn"t be a surprise to see this kind of market behaviour." The FTSE 100 has added 10.3% so far this year, but is still 8% away from its record highs hit in 2018 as an economy slowing due to weaker consumer demand, and risks around central banks pulling back monetary support sooner than expected, have weighed on the FTSE 100 recently. In a bright spot, official data showed that British retailers saw the biggest surge in spending in almost seven years this month and orders hit a new high.
