LONDON, March 18 (Reuters) - Top London shares were flat at midday on Wednesday, with further optimism in the banking sector offset by unemployment in Britain hitting a 12-year high of more than 2 million in February, above forecasts.

> was up 0.72 points, or 0.02 percent at 3,857.82.The number of people claiming jobless benefit in February jumped by the biggest amount since records began in 1971, and the wider measure of unemployment rose above 2 million for the first time since 1997. [
]"The unemployment numbers were worse than expected and truly horrendous in what they say about the state of the UK economy. But the FTSE is more of an international index rather than just a reflection of the UK, and it seems to have affected sterling more," said Henk Potts, strategist at Barclays Wealth.
The FTSE 100 index has risen more than 11 percent since falling to a six-year low last week, but is still down more than 13 percent in 2009, hurt by a banking crisis and the recession.
Royal Bank of Scotland <RBS.L> was up 8.1 percent after chairman Philip Hampton told the Financial Times newspaper it had benefited from "buoyant" corporate banking activity in its key markets in 2009. [
]RBS, 70-percent owned by Britain, is the latest bank to be more upbeat following a period of turmoil for the sector.
"In terms of the banking sector, you could say we're not out of the woods yet, but at least the trees have stopped falling on us," said Potts.
On Tuesday, HSBC <HSBA.L> said trading continued to be strong, helping its shares to their highest close since Feb. 27, just before it announced a 12.5 billion pounds rights issue.
Barclays <BARC.L> rose 5.8 percent, while Standard Chartered <STAN.L> was up 0.8 percent. HSBC, trading ex-dividend on Wednesday, lost 1.6 percent.
Land Securities <LAND.L> and Standard Life <SL.L> also dipped after going ex-dividend. Insurers rose as global equity markets picked up. Old Mutual <OML.L>, Aviva <AV.L> and Legal & General <LGEN.L> were up 1.4-7.2 percent.
OILS GAIN
Oils were higher, with crude prices <CLc1> rising to $49 a barrel in the United States on Tuesday, though they eased back slightly on Wednesday.
BP <BP.L> and Cairn Energy <CNE.L> were up 1.9 and 2.3 percent respectively.
Among midcaps, Venture Production <CVPC.L> soared 26 percent after Centrica <CNA.L> bought a 22 percent stake for 239 million pounds and said it may make a cash offer for the company.
All nine members of the Bank of England's Monetary Policy Committee voted this month to launch a 75 billion pound asset-buying programme and to cut interest rates by 50 basis points to a record low of 0.5 percent, minutes published on Wednesday showed. [
