* FTSEurofirst 300 index down 0.6 percent
* Unexpected contraction in Q4 UK GDP hurts confidence
* Spanish banks hit by capital worries

LONDON, Jan 25 (Reuters) - European shares fell on Tuesday, as confidence in Britain was shaken by an unexpected drop in fourth-quarter UK growth figures and with Spanish banks down on concerns new capital requirement rules may not be tough enough.
Britain's economy unexpectedly shrank 0.5 percent in the last three months of last year, the first quarterly drop since the third quarter in 2009, prompting warnings of a grim 2011 as the government embarks on the deep spending cuts.[
]The pan-European FTSEurofirst 300 <
> index of top shares closed 0.6 percent lower at 1,144.14 points."Everyone is on the back foot given the GDP numbers earlier, which has certainly capped any upside for the market. There doesn't seem to be much in the way of fresh buyers around which begs the question where is the new wave of buying going to come from," said Manoj Ladwa, senior trader at ETX Capital.
British retailers were among the worst hit by the disappointing growth figures, with Marks & Spencer <MKS.L>, Next <NXT.L> and Kingfisher <KGF.L> down 0.9 to 3.1 percent.
Encouraging macroeconomic data from the United States, however, helped limit further losses on the index, as figures showed consumer confidence rose more than expected in January to its highest level in eight months.
Across Europe, Britain's FTSE 100 <

CAPITAL RATIO WORRIES
Spanish banks were under pressure after Spain's Economy Minister Elena Salgado said late on Monday that the country's savings banks have to boost core capital ratios to a minimum of 8 percent by September or the state will partially take them over. [
]Banco Santander <SAN.MC> and BBVA <BBVA.MC> underperformed the wider banking sector by falling 3.1 and 2.9 percent on concerns the new capital requirements ratios may not be tough enough to build confidence in the sector.
"There has been quite a bit of optimism around the European crisis over the past few days, but there is still a great deal of concern over the Spanish cajas. If they can't find the funding, this will have a dire effect on the rest of Europe," said Angus Campbell, head of sales at Capital Spreads.
Offering some relief from the gloom over the debt crisis in the euro zone, the European Financial Stability Facility (EFSF) drew extremely high demand for its debut issue of five-year debt to fund Ireland's bailout, with order books worth over eight times the amount on offer. [
]Among individual movers, French chip maker STMicroelectronics <STM.PA> lost 4.5 percent as disappointing performance of its joint venture with Ericsson <ERICb.ST> and a downbeat outlook for revenue in 2011 weighed on the stock, despite posting better-than-expected fourth-quarter results.
Ericsson, however, gained 2.5 percent after fourth-quarter sales surged and the company forecast strong demand for mobile broadband equipment in 2011. [
