                             London Stock Exchange plc


Unless otherwise stated, the following commentary refers to the 11 months ended
28 February 2006 and, where appropriate, to the corresponding period last year.

London Stock Exchange plc ("the Exchange") today issued its update ahead of the
close period relating to the year ending 31 March 2006.

In summary, trading performance continues to be very strong, benefiting from
increasingly positive trends in all core business areas:
     
•    Total new issues up 25 per cent to 547; total money raised up 124 per cent 
     to £18.2bn

•    Average daily number of SETS bargains increased 29 per cent to 216,000 and 
     average daily value traded up 29 per cent to £4.5bn

•    Professional terminals at 87,000 - up 4,000 since February 2005 and 1,000 
     since December 2005

Of particular note is the recent acceleration of activity on SETS - in Q4 to
date average daily SETS bargains are up 38 per cent to 272,000.  January and
February both delivered record levels of value and volume traded on SETS, which
March will exceed.

Commenting on current trading and outlook, Clara Furse, Chief Executive, said:

"The strong performance of the first nine months of the financial year has
improved further still in the last quarter and, as expected, we are on track to
deliver an excellent outcome for the current financial year.  In particular, the
recent acceleration of growth on SETS means that trading in March will exceed
all previous records by a significant margin.  Our business goes from strength
to strength creating more value by the day."

The total number of new issues grew strongly in the eleven months to 28 February
2006, increasing 25 per cent to 547 (2005: 436).  New issues on the Main Market
rose 30 per cent to 95 (2005: 73) and on AIM, the world's most successful growth
market, they increased 23 per cent to 448 (2005: 363).

Reflecting the Exchange's position as the international listing venue of choice,
the total number of overseas companies joining our markets was up 77 per cent at
131 (2005: 74).

Total money raised on our markets more than doubled during the period at £18.2bn
(2005: £8.1bn).

At 28 February 2006, the total number of companies on the Exchange's markets was

Growth on SETS, the electronic order book, accelerated over the period,
benefiting from a secular shift in the pattern of trading, facilitated by
investment by the Exchange in a new technology platform.  Eighteen of the twenty
busiest trading days ever recorded on SETS occurred following the introduction
of Infolect in September and an increase in trading capacity in October.
Trading in March will break previous records by a significant margin.

In the eleven months to 28 February 2006, the average daily number of SETS
bargains increased 29 per cent to 216,000 (2005: 167,000) and average daily
value traded increased 29 per cent to £4.5bn (2005: £3.5bn).  Record levels were
achieved in January (258,000 bargains/day; £5.6bn), and again in February
(267,000 bargains/day; £5.8bn).  Very strong growth on SETS has followed in
March, with average daily bargains to date of 293,000 (2005: 207,000), up 42 per
cent.

The average value of a SETS bargain during the period was steady at £21,000
(2005: £21,000).  At just over £1.50, the average SETS yield was broadly in line
with the same period last year.

In the circular to shareholders dated 17 February 2006, the Exchange stated that
the average number of trades per day on SETS is expected to increase by at least
50 per cent in financial year 2007 and 100 per cent in financial year 2008,
relative to financial year 2005.  The rate of growth in average SETS bargains
per day achieved so far in Q4 - 38 per cent to 272,000 (2005: 197,000) - is well
ahead of the rate required to meet these targets.

Reflecting very strong performance by SETS, the average total number of equity
bargains per day increased 28 per cent to 341,000 (2005: 266,000).  Total value
traded was £5.1tn, up 19 per cent on the previous year (2005: £4.3tn).

The average number of off-book bargains was 46,000 per day (2005: 48,000) and
the average number of international bargains was 78,000 per day (2005: 51,000).

Demand for real-time data continues to grow steadily and at 28 February 2006,
the total number of terminals receiving Exchange data was 102,000, an increase
of 8,000 over the same point last year (28 February 2005: 94,000).  Of the
total, approximately 87,000 terminals were attributable to the professional user
base, up 4,000 since February 2005 and 1,000 since the end of 2005 (31 December
2005: 86,000; 28 February 2005: 83,000).

Recent initiatives also delivered additional growth.  At 28 February, Proquote
had 3,000 screens, an eleven per cent increase on the same time last year (28
Feb 2005: 2,700 screens).

SEDOL Masterfile, the Exchange's global securities numbering service, continues
to perform very well, with over 1,100 licences signed and 1.1 million securities
covered.

year increased strongly by 16 per cent to 19.8 million (2005: 17.1 million).
