LONDON, Feb 9 (Reuters) - A fall in the shares of major banks and mining stocks kept Britain's top share index near three-year lows on Tuesday, as concerns lingered over the global economy and the health of the financial sector.

The blue-chip FTSE 100 index, fell 0.3 percent to 5,671.35 points by 1151 GMT, remaining close to its lowest level in around three years.

A drop in heavyweight banking stocks such as Barclays (Swiss: BARC.SW - news) and HSBC curbed the FTSE's recovery, with the FTSE 350 Banks Index index down 1.1 percent, hitting its lowest level since November 2011.

Mining stocks also fell sharply, with Anglo American (LSE: AAL.L - news) down 9.9 percent after Anglo American's Kumba division posted lower profits, and Antofagasta (Other OTC: ANFGF - news) falling 10 percent after Goldman Sachs (NYSE: GS - news) cut its rating on the stock to "sell".

Signs of a global economic slowdown have hit world stock markets since the start of the year, and raised concerns about the stability of the European banking system.

"There are worries about global growth, and fears of a recession are starting to emerge. The banks are getting hit hard," said Richard Griffiths, associate director at Berkeley Futures.

Goldman Sachs analysts wrote that while there were no signs of any strain in terms of euro or U.S (Other OTC: UBGXF - news) . dollar funding in money markets for European banks, market liquidity had nevertheless reduced.

Exane BNP Paribas also cut its price targets on Barclays (LSE: BARC.L - news) , HSBC, Lloyds, Royal Bank of Scotland (LSE: RBS.L - news) and Standard Chartered (BSE: 580001.BO - news) , citing the pressures on the sector.

Among the top gainers, however, Legal & General (LSE: LGEN.L - news) was up 2.5 percent after it clarified its exposure on its bond portfolio as at Dec (Shanghai: 600875.SS - news) . 31, reassuring investors.

UK supermarkets were also in focus, with Tesco gaining 2.4 percent after data from Kantar Worldpanel indicated that the company's sales showed signs of improvement in the early weeks of the year, as the supermarket had its best outcome since September last year.

The data also showed that Sainsbury (Amsterdam: SJ6.AS - news) continued to outperform its rivals in the same time period and posted higher sales. Shares (Berlin: DI6.BE - news) in the company advanced 0.6 percent.

Likewise shares in WPP (Swiss: OXWPP.SW - news) , the world's largest advertising company, rose 2.4 percent following a sell-off in the previous session.

JPMorgan made a case for a higher valuation of the company, saying that the current valuation did not reflect its resilient earnings per share growth.

The FTSE 100 hit a record high of 7,122.74 points in April (LSE: 0N69.L - news) 2015 but has steadily lost ground since then. The index is down 20 percent from that record level and down nearly 10 percent since the start of 2016. (Editing by Keith Weir)
