FTSE slips as banks plan Europe-wide platform

A plan by seven leading investment banks to set up a Europe-wide share-trading platform put pressure on shares in the London Stock Exchange today.

The stock slipped 8% in the FTSE 250 Index, offsetting a promising session for the rest of the London market after a gain of 26.7 points for the FTSE 100 to 6213.3 mid-morning.
