In order to utilize the "Safe Harbor"  provisions  of the United States  Private
Securities  Litigation Reform Act of 1995 (the "Reform Act"),  Marconi plc ( the
"Company")  is  providing  the  following  cautionary   statement.   Except  for
historical information contained herein,  statements contained in this Report on
Form 6-K may constitute  "forward-looking  statements" within the meaning of the
Reform Act. The words "believe",  "anticipate",  "expect", "intend", "estimate",
"plan",  "assume",  "positioned",   "will",  "may",  "risk"  and  other  similar
expressions which are predictions of or indicate future events and future trends
which do not relate to historical matters identify  forward-looking  statements.
Reliance should not be placed on such statements  because they involve known and
unknown  risks,  uncertainties  and other factors which are in some cases beyond
the control of the Company,  together with its subsidiaries  (the "Group"),  and
may cause the actual results, performance or achievements of the Group to differ
materially  from  anticipated   future  results,   performance  or  achievements
expressed or implied by such forward-looking  statements (and from past results,
performance or  achievement).  Certain  factors that may cause such  differences
include  but are not  limited  to the  following:  (1) any major  disruption  in
production  at our key  facilities;  (2) changes in the  environmental,  tax and
other laws and regulations,  which, among other things,  could cause us to incur
substantial additional capital expenditures and operation and maintenance costs;
and (3) adverse  changes in the markets for our products,  including as a result
of increased  competition in the highly  competitive  international  markets for
such products. These and other risks, uncertainties and factors are discussed in
the  Company's  Registration  Statement  on Form F-1 and other  filings with the
Securities and Exchange  Commission,  including this Form 6-K.  Shareholders and
prospective  investors  are  cautioned  not to  place  undue  reliance  on these
forward-looking  statements which speak only as to the Company's  judgment as of
the date hereof.  Any such  forward-looking  statements are not intended to give
any  assurance as to future  results.  The Company  undertakes  no obligation to
publicly update or revise any of these  forward-looking  statements,  whether to
reflect new information or future events or circumstances or otherwise.

                              RESTRUCTURING UPDATE

                           Results of Creditor Voting

   - Scheme creditors of Marconi Corporation plc and Marconi plc have voted
    overwhelmingly to approve the schemes of arrangement with a very high level
    of turnout

   - 99.98 per cent by value and 94.71 per cent by number of Marconi
    Corporation plc scheme creditors who voted at the meeting voted in favour of
    the Marconi Corporation plc scheme

   - 99.97 per cent by value and 93.60 per cent by number of Marconi plc
    scheme creditors who voted at the meeting voted in favour of the Marconi plc

John Devaney, Chairman of Marconi plc, said "The overwhelming support received
from our creditors today demonstrates clearly that they share our belief in the
inherent value of Marconi as an ongoing business. We now move on to achieving
the final legal approvals from both the UK and US courts, which will clear the
way for the re-listing of Marconi, which is currently expected to take place on
19 May 2003."

London - 25 April 2003 - The creditor groups of Marconi plc ("plc") (MONI) and
Marconi Corporation plc ("Corp") today voted overwhelmingly to support its
financial restructuring. At separate meetings of scheme creditors of plc ("plc
Scheme Creditors") and Corp ("Corp Scheme Creditors") (the "Scheme Meetings"),
the schemes of arrangement in relation to each of plc and Corp (the "Schemes")
were approved by a majority in number representing more than the required 75 per
cent in value of the scheme creditors present and voting (either in person or by
proxy) (the "Requisite Majorities") at the respective Scheme Meetings. Approval
of the Schemes by the Requisite Majorities is a key pre-condition for the
Schemes becoming effective. The Corp Scheme is not conditional on the plc Scheme
becoming effective. However, the plc Scheme will not become effective unless the
Corp Scheme becomes effective.

In order for the Schemes to become effective and legally binding, UK Court
orders sanctioning the Schemes must also be obtained. The Court orders must then
be sealed and copies delivered for registration to the Registrar of Companies in
England and Wales. The UK Court hearing to sanction the Schemes is currently
scheduled to begin on 12 May 2003.

Corp and plc will not take the necessary steps to make the Schemes effective
unless, inter alia, permanent injunction orders of the US Bankruptcy Court are
obtained in respect of the Schemes and all other conditions precedent under the
working capital and performance bonding facilities are satisfied or waived. The
US Bankruptcy Court hearing is currently scheduled to take place on 14 May 2003.

It is currently expected that the Schemes will become effective, with trading in
the new securities to be issued by Corp commencing on the London Stock Exchange
on 19 May 2003.

The figures set out below represent the final results of the voting by scheme
creditors, either by proxy or in person, at the Scheme Meetings.


The result of the voting by the Corp Scheme Creditors present and voting (either
in person or by proxy) at the Corp scheme meeting is as follows:

          Value of Votes    Number of Votes

 FOR        99.98%            94.71%

 AGAINST     0.02%             5.29%

 Total      100.0%            100.0%


The result of the voting by the plc Scheme Creditors present and voting (either
in person or by proxy) at the plc scheme meeting is as follows:

          Value of Votes    Number of Votes

FOR           99.97%             93.60%

AGAINST        0.03%              6.40%

Total         100.0%             100.0%
