LONDON (Reuters) - Borse Dubai has launched an accelerated sale of 8.5 million shares in the London Stock Exchange (>> London Stock Exchange Group Plc), representing around 3.1 percent of the company's issued capital, two sources familiar with the matter said on Thursday.

The latest price guidance on the shares is 20.20 pounds each, one of the sources said, valuing the stake at 171.7 million pounds and representing a 3 percent discount to the closing price of 20.85 pounds.
