* FTSE 100 index flat; commodity issues rally
* Banks weak on European debt uncertainties
* Ex-dividends weigh led by M&S, Vodafone
By Jon Hopkins
LONDON, Nov 17 (Reuters) - Britain's leading share index was flat at noon on Wednesday, with weakness in banking issues on Europe's debt problems, and ex-dividemd factors offsetting a modest rally by commodity issues.
By 1159 GMT, the FTSE 100 <
> was 2.13 points, or 0.1 percent, lower at 5,679.77, licking its wounds after notching up its biggest daily fall since August 11 on Tuesday."There are few people who had not expected some form of correction after the rapid rise following the Fed's announcement of QE2," said Phil Gillett, a trader at Spreadex.
"What seems different this time is the market's lack of desire to drive north on this drop. Having broken (down) through the 5,700 level, the market looks now to be at a turning point and the risk remains to the downside."
Banks were under pressure <.FTNMX8350> as investors continued to fret over their exposure to Europe's debt troubles. Global heavyweight HSBC <HSBA.L> was the worst off, down 0.8 percent, with the stock trading ex-dividend on Wednesday.
Market heavyweight Vodafone <VOD.L> was the biggest drag on the blue chips, down 2.2 percent also after losing its payout attractions, and as Evolution Securities cut its rating for the mobile telecoms firm to "reduce" after recent results. "Despite slightly better than expected results, we see some potentially large macroeconomic stumbling blocks and still too little evidence that Vodafone is sufficiently differentiated from peers to deserve a premium rating," the broker said.
Marks & Spencer <MKS.L>, J Sainsbury <SBRY.L>, Barclays <BARC.L> and Carnival <CCL.L> also traded ex-dividend.
The number of Britons claiming unemployment benefit fell unexpectedly last month and a wider measure of unemployment also fell in the three months to September, official data showed on Wednesday. [
]Meanwhile, Bank of England policymakers split three ways for a second month running in November, with one member wanting more stimulus, another voting for a rate hike, and other seven freezing policy and ready to act in either direction. [

COMMODS RALLY
Mining <.FTNMX1770> and energy <.FTNMX0530> stocks ticked higher, recovering support after recent falls made on the back of fears of interest rate hikes in China, the world's largest commodities consumer. [
]Xstrata <XTA.L> was the best-performing miner, up 1.1 percent, while energy firm BG Group <BG.L> gained 0.5 percent.
Drugmaker GlaxoSmithKline <GSK.L> provided the most underlying strength for the FTSE 100 index, gained 2.1 percent following backing from a U.S. advisory panel for its lupus drug Benlysta, which is seen as a potential blockbuster. [
]Credit information group Experian <EXPN.L> was the top blue-chip performer, up 6.5 percent after hiking its interim dividend and saying it continued to look at ways of returning cash to shareholders after a stronger-than-expected first half. [
]Inter-dealer broker Icap <IAP.L> gained 2 percent after saying it had shrugged off "generally quieter markets" in the six months to end-September to report revenue up 9 percent at 867 million pounds. [
