LONDON, Aug 4 (Reuters) - Britain's top shares were down sharply by midday on Wednesday as a deluge of corporate results from London's blue chips failed to counter investors' concerns about the sustainability of economic recovery in the United States.
By 1041 GMT, the FTSE 100 <
> was 60.70 points, or 1.1 percent, lower at 5,335.78, having closed flat at 5,396.48 in the previous session."This (fall) is a very short-term issue relating to the loss of recovery momentum," said Mike Lenhoff, chief strategist and head of research at Brewin Dolphin Securities.
"The big question mark is over where this (concerns about the U.S. economy) is going to lead -- is this just another stage of the cycle or is this going to head into a double dip?"
Energy and mining stocks were the biggest fallers on London's blue chip index as downbeat data from the United States sapped appetite for risk and hit demand for commodities.
Oil majors BG Group <BG.L> and BP <BP.L> were down 1.3 and 1.4 percent, respectively, along with crude <CLc1>, while peer Royal Dutch Shell <RDSa.L> lost 1.6 percent, also after a power trip disrupted operations at its new 800,000 tonne-per-year ethylene cracker on Singapore's Bukom island.
Miners Antofagasta <ANTO.L>, which reported second-quarter output figures, and Anglo American <AAL.L> were among the worst performers in the sector off 3.4 and 2.0 percent, respectively.
Data on Tuesday showed U.S. pending home sales slid to a record low in June, while consumer spending and personal incomes were flat.
U.S. stock index futures pointed to a lower open for Wall Street on Wednesday, as investors awaited the ADP Employment figures for July, due at 1215 GMT to gauge the health of the U.S. labour market ahead of non-farm payroll numbers on Friday.
STANDARD RESULTS
Banks were led lower by Standard Chartered <STAN.L>, which fell 6.9 percent despite beating expectations with its first-half earnings. Analysts said the beat was mainly due to lower bad debts and further upside could be limited due to its premium rating already. [

Barclays <BARC.L> was down 2.0 percent ahead of results on Thursday, and HSBC <HSBA.L> shed 1.4 percent.

Insurer Legal & General <LGEN.L> fell 2.3 percent as Citigroup pointed to slowing growth, following the insurer's first-half results, and reiterated its "sell" stance. [

Britain's No.2 fashion retailer Next <NXT.L> was down 7.6 percent, topping the FTSE fallers list, after the company said a fall in first-half underlying sales would deepen in the second half and warned shoppers also faced a hike in clothes prices next year. [
]Mid cap Carpetright <CATVU.L>, Britain's biggest floor coverings chain, shed 2.0 percent after it also reported a drop in underlying sales and said it was planning for spending to stay subdued for the rest of 2010.
Retailers Marks and Spencer <MKS.L>, Home Retail <HOME.L> and Kingfisher <KGF.L> dropped 3.0 to 3.8 percent.
