Misleading information which allegedly resulted from technical problems was published on Wednesday causing confusion in trading on the London Stock market.

For the first time, trading on the London Stock Exchange (LSE) was extended to late 1800 GMT after all the terminals in the City displayed incorrect prices which showed the benchmark FTSE 100 closing up on Wednesday, although it was sharply down for almost the whole day.

The confusion affected price information which providers such as Bloomberg sell on to traders and other city professionals.

After half an hour of misleading information, trading showed the FTSE 100 down 54.8 points at 6420.1 with shares of leading banks and mortgage lenders under continuing pressure.
