* Miners slip, tracking lower metal prices
* Debenhams surges on trading update

LONDON, June 24 (Reuters) - Britain's blue-chip index fell 1.3 percent by midday on Tuesday as banking stocks slipped ahead of a rate decision by the U.S. Federal Reserve on Wednesday and political tension between Israel and Iran weighed on the market.
By 1119 GMT the commodity-heavy FTSE 100 <
> was down 73.7 points at 5,593.5, after rising 0.8 percent on Monday.The market extended early losses on rumours of a strike on Iran's nuclear sites. The denial of the rumour by a senior Iranian nuclear official had little market impact. Last Friday the New York Times quoted U.S. officials as saying Israel had carried out exercises which could be a rehearsal for a strike on Iran.
Investors remained cautious ahead of a U.S. Federal Reserve statement on Wednesday that could shed light on the timing of possible interest rate increases.
"Investor confidence seems to be drifting lower with practically every sector in the UK being sold off, perhaps in preparation for this week's main event the Fed's interest rate meeting," Sam Goult, a trader at CMC Markets, said in a note.
Banks were the top losers on the FTSE 100 index, with Standard Chartered <STAN.L> falling 3.1 percent, Royal Bank of Scotland <RBS.L> declining nearly 1 percent and Lloyds TSB <LLOY.L> dropping 1.2 percent.
HSBC <HSBA.L> fell 1.1 percent after traders referred to market rumours that the British bank could make a bid for the world's largest wealth manager UBS <UBSN.VX>.[
]But Bradford & Bingley <BB.L> soared nearly 15 percent after restructuring specialist Resolution said it planned to consolidate some of Britain's smaller banks and had been invited by investors in Bradford to consider using it to spearhead the plan. [
]Bradford rejected the investment approach, saying it would have meant Resolution taking effective control of the lender. Bradford shares were last up 10 percent.
Analysts said the market outlook remained dull.
"We are now realising that the build up of inflationary pressures presents major issues on all non-oil producing economies, not just the major western group," said Roger Cursley, UK strategist at Investec.
"And I don't think this is really being reflected in stocks market pricing so far this year, as most of the pressure had been around the credit crisis or domestic consumer demand in the UK and the U.S. It's suggestive of a very difficult second half of the year."
MINERS SUFFER
Miners slipped, tracking weaker metal prices. BHP Billiton <BLT.L>, Xstrata <XTA.L>, Anglo American <AAL.L> and Vedanta Resources <VED.L> fell between 0.7 and 3.7 percent.
But Antofagasta <ANTO.L> gained 0.6 percent after Credit Suisse upgraded the stock to "outperform" from "neutral" and raised its price target to 760 pence from 600 pence.
Oil shares also tracked a broader decline in the market despite a rise in crude prices. BP <BP.L>, Royal Dutch Shell <RDSa.L> and Cairn Energy <CNE.L> all dipped between 0.4 and 1.8 percent.
British gas producer BG Group <BG.L> fell 1.9 percent after it launched a hostile $13.1 billion bid for Australia's Origin Energy <ORG.AX>, as it sought to boost its position in Asia-Pacific's fast-growing gas market. [
]Retailers suffered, with Britain's biggest retailer Tesco <TSCO.L>, J Sainsbury <SBRY.L> and Britain's fourth biggest supermarket group, Wm Morrison <MRW.L>, all falling between 1.7 and 2.9 percent.
But Debenhams <DEB.L> jumped as much as 16 percent after the department stores group said like-for-like sales rose a stronger-than-expected 1 percent in the last 10 weeks and its net debt would be in line with analysts' current expectations. But stocks pared gains and were last up 0.6 percent.
Advertising group WPP <WPP.L> said like-for-like revenues rose 4.5 percent and forecasts were in line with full year margin target. [
