                           CANWEST APPOINTS NEW CHAIR

                David Drybrough named interim Chair of the Board,
                        replacing the Hon. Frank McKenna

WINNIPEG: CanWest Global Communications Corp. announced today the appointment of
David  Drybrough,  F.C.A,  as  Interim  Chair  of its  Board of  Directors.  Mr.
Drybrough replaces the Hon. Frank McKenna, who has resigned his position to take
up the post as Canada's Ambassador to the United States of America.

Mr.  Drybrough is a Winnipeg  native and was Chief  Financial  Officer of Gendis
Inc., a public company,  until December 2003. Mr. Drybrough retired as a partner
in the accounting  firm Coopers & Lybrand,  now known as  PricewaterhouseCoopers
LLP in 1997.  He has served on the  CanWest  Board since March 2003 and has been
associated with the company for many years. He has served on the Company's Audit
Committee  since his  appointment  to the Board and will retain his  position as
Chair of that Committee.

Leonard Asper, CanWest's President and Chief Executive Officer, announced at the
Company's  recent  Annual  General  Meeting  of  shareholders  that  one  of the
Company's current independent directors would be appointed Interim Chair. "David
Drybrough brings to this role impeccable credentials and a deep understanding of
our Company.  We are pleased that he has agreed to take on this leadership role,
pending a decision by the Board on a permanent appointment," commented Asper.

"I would  also  like to take a moment to  re-iterate  the  comments  made at the
recent AGM,  thanking Frank McKenna for six years of stellar service to CanWest,
its Board of Directors,  and its  shareholders,"  added Asper.  "His  leadership
through a extraordinary  period of growth in the Company's  history will be long
remembered.  We are a better  Company  today because of his service to the Board
and his tenure as Chair."

Asper also noted that the  CanWest  Board of  Directors  will  continue  to seek
independent  directors to fill  vacancies  created by Ms.  Jalynn  Bennett,  who
decided  not to stand for  re-election  at the  Company's  recent  AGM,  and the
resignation of Mr. McKenna.
