LONDON, Feb 26 (Reuters) - The FTSE 100 <
> index of Britain's leading shares clung on to earlier gains on Tuesday, despite a surprise fall in retail sales, as results from Standard Chartered <STAN.L> buoyed banks and financial stocks.At 1138 GMT the blue-chip index was up 64.7 points, or 1.1 percent at 6,064.2 to extend a near 2 percent rise from the previous session and puncture the psychologically key 6,000 level.
However, the index slipped slightly midway through the session after British retail sales unexpectedly fell in February for the first time in more than a year. [
]Banks and financials featured prominently on the upside, with Alliance & Leicester <ALLL.L> jumping 5.1 percent while HSBC <HSBA.L> and Royal Bank of Scotland <RBS.L> rose over 3.5 percent.

Aviva <AV.L> and Old Mutual <OML.L> added between 4.2 and 3.9 percent, respectively.
On Monday, U.S. stocks gained more than 1 percent on hopes that U.S. bond insurers will keep their credit ratings, offering relief to investors still wary of further bank writedowns.
Standard & Poor's removed its threat to downgrade MBIA's "AAA" rating, while rival Ambac Financial Group was reported to be near a deal to shore up its financial position.
"This has been entirely a sentiment move based on perceived support from banks and rating agencies for the mono-line insurers," said David Buik of Cantor Index.
"Sentiment is much improved, but can it be sustained? This credit crisis is a long way from being sorted out and may well require some positive input from the world's central banks to get the show back on the road," he added.
It should not be forgotten that volumes this morning are, not for the first time, utter rubbish."
About 30 percent of the average daily trading volume of the last 30 days had gone through by 1214 GMT.
