LONDON, Nov 5 (Reuters) - Britain's top shares fell 0.5 percent around midday on Thursday, as investors digested the Bank of England decision to keep interest rates on hold and said it will pump more money into the economy to spur growth.

By 1228 GMT the FTSE 100 .FTSE was down 25.00 points at 5,082.98. The BoE left interest rates unchanged at 0.5 percent, while notching up its quantitative easing programme to 200 billion pounds.

The index initially extended its losses after the announcement, but settled back around levels seen before the rate decisions.

"The announcement is as expected. It's largely flagged by the market and that's indicated by a very flat movement on the news," said Tim Whitehead, head of portfolio services at Redmayne-Bentley.
