* Miners, oils lifted by firmer commodity prices
* Whitbread up on bullish trading statement

LONDON, Dec 14 (Reuters) - Gains in banks and commodity stocks lifted Britain's top share index 0.8 percent by midday on Monday, after Abu Dhabi bailed out neighbouring Dubai with $10 billion in surprise aid, settling investor nerves.
By 1202 GMT, the FTSE 100 was 41.01 points higher at 5,302.58, adding to gains from the previous session when it ended up 17.20 points, or 0.3 percent.
Investors bought banks as anxiety about their exposure to Dubai's debt problems eased. Standard Chartered <STAN.L> fared best, up 3.5 percent, supported too by a Credit Suisse upgrade, while HSBC <HSBA.L> and Barclays <BARC.L> added 2.1 and 1.1 percent respectively.
Dubai said funds provided by its neighbour Abu Dhabi would help towards repaying a $4.1 billion Islamic bond maturing on Monday, while the excess would be used to meet state-owned conglomerate Dubai World's needs up until the end of April 2010. [
]"People are focused on the financing from Abu Dhabi and the effect that it's having on sentiment as it's increasing the desire for risk," said Henk Potts, analyst at Barclays Wealth.
He added that stronger-than-expected data from the United States and China last week and relatively low valuations were also supportive of equities as an asset class.
But Lloyds Banking Group <LLOY.L> lost 1.3 percent as underwriters offered in the market the rump of the bank's record rights issue which the group said on Monday had achieved a 95 percent take-up. [
]Royal Bank of Scotland <RBS.L>, majority-owned by the state, also lost 1.3 percent.
However other financial sector shares found support, with the London Stock Exchange <LSE.L> the top FTSE 100 riser, up 7.6 percent as worries that shareholder Dubai Bourse might have to sell its stake in the British firm receded.
Insurers Prudential <PRU.L>, Aviva <AV.L>, and Standard Life <SL.L> added 1.4 to 3.1 percent.
COMMODITIES GAIN
Heavyweight commodity stocks gained too as the demand picture continued to improve, helped again by last week's solid data from major consumer China.
Among the miners, Lonmin <LMI.L>, Vedanta Resources <VED.L>, BHP Billiton <BLT.L>, Anglo American <AAL.L>, Rio Tinto <RIO.L> and Xstrata <XTA.L> gained 0.8 to 2.3 percent.
Oil majors BG Group <BG.L>, BP <BP.L>, and Royal Dutch Shell <RDSa.L> added 1.1 to 1.2 percent.
Whitbread <WTB.L> stood out among individual gainers, up 3.4 percent after the hotels to coffee shops operator said in a trading update that it expected its 2009/10 results to "somewhat exceed" market estimates. [
].With no significant economic data released in the UK, or due in the United States on Monday, the macro focus was on the latest two-day Federal Reserve meeting, which kicks off on Tuesday, with an interest rate decision due after the London close on Wednesday.
"No one has a really strong reason to be selling equities at the moment, and after the recent surprisingly upbeat U.S. non-farm payrolls (employment) report things could surprise on the upside for now," said David Morrison, market strategist at GFT Global.
Among the losers, British Airways <BAY.L> fell 0.7 percent after the airline said its pension deficit more than doubled to 3.7 billion pounds ($6 billion) at the end of March, but not seen as big enough to detail a merger with Spain's Iberia <IBLA.MC>.
The airline is also awaiting the release of the results of a strike ballot by its cabin crew, due later this afternoon. [
