* FTSE down 1.6 pct after BoE report echoes Fed sentiment
* Banks biggest fallers
* Miners, energy firm slide as data hit commodities demand

LONDON, Aug 11 (Reuters) - Britain's top shares were sharply lower at midday on Wednesday, as banks led a broad-based sell-off after the Bank of England (BoE) inflation report echoed worries in the U.S. over the economic recovery.
By 1046 GMT the FTSE 100 <
> index was down 85.86 points, or 1.6 percent, at 5,290.55, having shed 0.6 percent to 5,376.41 on Tuesday.Banks were the hardest hit as the BoE indicated that interest rates would remain low for longer and it lowered its forecasts for Britain's economic growth.
Lloyds Banking Group <LLOY.L>, Barclays <BARC.L> and Royal Bank of Scotland <RBS.L> fell 3.0-3.6 percent.
British inflation will fall to well below its 2 percent target in two years, even if interest rates remain at their record low, the Bank of England forecast on Wednesday, leaving scope for further policy easing if the economy worsens. [
]Growth is expected to be slower -- seen at a rate of just over 3 percent in two years' time, down from 3.6 percent -- because of the extra fiscal tightening announced in the June budget, weaker business and consumer sentiment and credit conditions remaining tighter than the central bank had expected.
"Markets have been struggling to see the positives for the last few days and they have looked vulnerable ... What we have seen in the last 24 hours has added to concerns that the stock market recovery has got ahead of the real recovery," said David Jones, chief market strategist at IG Index.
Earlier, the Office for National Statistics said the number of people claiming jobless benefit fell in July, though the pace of improvement is unlikely to be maintained once government spending cuts kick in, leading to public sector job losses tipped to exceed half a million. [

U.S. CONCERNS
Markets were already under pressure after the U.S. Federal Reserve's Open Market Committee said on Tuesday it would use proceeds from maturing mortgage bonds to buy longer-term government debt to keep borrowing costs low. [
]The move, a stark warning that the recovery of the world's largest economy was losing pace, failed to convince investors the action would swiftly resolve a weak employment market or boost demand significantly.
"We were expecting major quantitative easing (QE), and what we got was QE light," said James Hughes, market analyst at CMC Markets.
U.S. stock index futures <SPc1> <DJc1> <NDc1> pointed to a lower open on Wall Street on Wednesday.
In London, energy and mining companies were weaker, in line with falling crude <CLc1> and metal prices, as the outlook for demand darkened.
Energy shares BP <BP.L>, Royal Dutch Shell <RDSa.L> and BG Group <BG.L> shed 0.7-2.0 percent.
An approaching storm in the Gulf of Mexico will delay by two to three days BP's work on a relief well to permanently plug the world's worst offshore oil spill, a U.S. official said on Tuesday. [
]Kazakhmys <KAZ.L>, down 3.1 percent, and Rio Tinto <RIO.L>, off 3.2 percent, were the top fallers in the mining sector.
Barclays <BARC.L>, BT Group <BT.L>, Rio Tinto <RIO.L> RSA Insurance <RSA.L>, Schroders <SDR.L>, Standard Chartered <STAN.L>, and Unilever <ULVR.L> all went ex-dividend, knocking a total of 6.1 points off the index.
Approaching midday, there were only three risers on the FTSE 100, with technology firm Smiths Group <SMIN.L> up 2.7 percent, extending the previous session's 2.1 percent rise, as traders cited hopes the group would be broken up after its successful restructuring. (Editing by Will Waterman)
