                    QIA INVESTS IN LONDON STOCK EXCHANGE

London Stock Exchange Group plc ('the Exchange') notes that the Qatar Investment
Authority (' the QIA') has acquired a 20 per cent holding in the company.  The
Board of the Exchange is very happy to welcome the QIA as a long term investor
in the company.

The QIA and the Exchange have a long standing relationship based on plans to
develop the Qatar marketplace and its potential for regional leadership in
financial services.  The Exchange believes that, given the strength of Qatar's
economy and the development of Doha as a major financial centre, there are
significant opportunities to build further this relationship to the mutual
benefit of both parties.

Clara Furse, Chief Executive of the Exchange, said:

'The QIA has an impressive track record of making substantial long term
investments in growth companies, so we are delighted to see that it recognises
the Exchange's unique strategic position and excellent prospects. We look
forward with confidence to delivering a full agenda and our wider global
strategy'.
