London  - The Bank of England (BoE) Thursday left interest rates unchanged at 0.5 per cent while deciding to pump an extra 25 billion pounds (41 billion dollars) into the economy to boost liquidity on the market.

The extra amount takes to 200 billion pounds the money injected into the market with the aim of increasing the money supply and stimulating the economy.

The bank's move was prompted by figures last month which showed that the British economy shrank by 0.4 per cent in the third quarter of 2009, dashing hopes of an early end to the recession, analysts said.(dpa)
