* Euro zone debt problems concern lingers
* Energy stocks lower as crude slips; ex-divs also weigh

LONDON, May 5 (Reuters) - A fall in energy stocks offset a minor rebound in mining stocks and banks to leave Britain's top share index lower at midday on Wednesday, as nerves on euro zone debt contagion lingered.
By 1056 GMT the FTSE 100 <
> was 9.19 points, or 0.2 percent lower at 5,401.92, down for a fourth consecutive session after it slid 2.6 percent on Tuesday to its lowest closing level in over two months.Equities have been dogged by fears European Union officials will not be able to stop Greece's sovereign debt crisis from spreading around the region. [
]The FTSE 100 index is now flat on the year, having been as much as 8 percent higher on April 16. A technical analyst at Charles Stanley said the next major support was at 5,259.
Miners were the main prop for the index as the sector recovered some of the losses from the previous two sessions prompted by plans for an Australian tax. Rio Tinto <RIO.L>, Xstrata <XTA.L>, Lonmin <LMI.L>, Vedanta Resources <VED.L> and BHP Billiton <BLT.L> gained 0.9-3.1 percent.
"Resources stocks are higher as they sold off sharply," said Geoff Wilkinson, head of research at Mint.
"The move down has caught a lot of people wrong and long, we have got a lot of work to do to stabilise as we may need to get through a residual overhang in selling."
Banks, also the targets of heavy selling in recent days, were broadly higher. HSBC <HSBA.L>, Lloyds Banking Group <LLOY.L> and Royal Bank of Scotland <RBS.L> added 0.6-1.2 percent, though Barclays <BARC.L> and Standard Chartered <STAN.L> fell.
Also within financials, Prudential <PRU.L> fell 1.3 percent after delaying a rights issue prompting a top 10 investor to call it "shambolic" and increasing concern about prospects for a $35.5 billion acquisition of AIG's <AIG.N> Asian life insurance unit.
Among blue-chip gainers, Home Retail Group <HOME.L> rose 1.6 percent after Morgan Stanley upgraded its rating for the stores group to 'equal-weight' from 'underweight', saying the stock looked oversold after the recent evaporation of M&A interest.
Energy giant BP <BP.L>, added 1.8 percent, despite going ex-dividend, recouping a small portion of heavy losses it has suffered as a result of fears on the costs associated with clearing up an oil spill in the Gulf of Mexico.
Panmure Gordon upped its rating for BP to 'buy' from 'sell'.
Ex-dividend factors weighed heavily, taking a hefty 18.47 points off the FTSE 100. Aside from BP, Antofagasta <ANTO.L>, Bunzl <BNZL.L>, G4S <GFS.L>, GlaxoSmithKline <GSK.L>, Kingfisher <KGF.L>, Wm Morrison <MRW.L>, Rexam <REX.L>, Royal Dutch Shell A <RDSa.L> and Royal Dutch Shell B <RDSb.L> shares all lost their payout attractions.
But while BP was buoyant, the weaker oil price <CLc1> weighed on explorers Tullow Oil <TLW.L> and Cairn Energy, down 0.8 percent and 1 percent respectively.
Power suppliers International Power <IPR.L> and Centrica <CNA.L> fell 2.2 percent and 1.1 percent respectively after Deutsche Bank downgraded its recommendations on both to 'hold' from 'buy'.
Shop price inflation accelerated sharply in April, driven by commodity prices rises, the reversal of a cut in value-added tax and the weak pound, a BRC survey found. [
