LONDON, April 3 (Reuters) - Britain's leading share index fell by midsession on Thursday after a three-day winning run as banks gave up recent gains, though commodity shares offered some support.
By 1043 GMT, the FTSE 100 <
> was down 27.2 points, or 0.46 percent at 5,888.7 after advancing nearly 4 percent in the previous three sessions."After the strong start we had to the week, particularly in the banks ... yesterday's comments from (Federal Reserve Chairman Ben) Bernanke mentioning for the first time that recession was a possibility casts a little bit of a shadow," said Richard Hunter, head of UK equities at Hargreaves Lansdown.
"We are not out of the woods yet but obviously it's looking much healthier than a few days ago. But the fact remains that the market is still down virtually 10 percent for the year."
Major European indexes were also weaker by midday.
Oil shares were the top gainers after crude prices <CLc1> steadied above $104 a barrel after surging almost $4 in the previous session on U.S. government data showing a sharp fall in refined fuel stocks.
Index heavyweight BP <BP.L> rose 1.3 percent, Royal Dutch Shell <RDSa.L> gained 1.4 percent and gas producer BG Group <BG.L> added 3.2 percent.
Miners were also standout gainers, tracking firmer precious metal prices. BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Anglo American <AAL.L>, Xstrata <XTA.L>, Antofagasta <ANTO.L> and Lonmin <LMI.L> were up between 0.3 and 1.9 percent.
Banks, however, languished after gains in recent sessions, with Barclays <BARC.L>, Royal Bank of Scotland <RBS.L>, HSBC <HSBA.L>, Lloyds TSB <LLOY.L>, HBOS <HBOS.L> and Standard Chartered <STAN.L> shedding between 1.5 and 4 percent.
Insurers were also down, with Royal & Sun Alliance <RSA.L> off 3.2 percent and Legal & General <LGEN.L> falling 3 percent.
Adding to investors' credit concerns, the Daily Telegraph said London-based hedge fund Polygon had introduced special measures to cope with the large number of investors asking to withdraw their money.
"We are a little bit lost for direction today. We might possibly see some profit taking ahead of non-farm (payroll figures from the U.S.) tomorrow," said Martin Slaney, head of derivatives at GFT Global Markets.
Property stocks fell after Lehman Brothers downgraded the European real estate sector and cut its 2008 net asset value estimates by an average 5 percent and price targets by 8 percent.
British Land <BLND.L>, Hammerson <HMSO.L>, Liberty International <LII.L>, Land Securities <LAND.L>, Segro <SGRO.L> and Great Portland Estates <GPOR.L> lost between 1.5 and 4 percent.
