TORONTO -- Postmedia Network Canada Corp. will no longer have publishers at three of its newspapers, as part of broad changes to centralize operations and reduce costs.

The media company, which owns several big city newspapers including the National Post, Vancouver Sun and the Ottawa Citizen, told staff that three publishers will leave the company as part of the changes.

Lou Clancy takes over editorial leadership as senior vice-president of content.

Postmedia says John Connolly, publisher of the Edmonton Journal; Guy Huntingford, publisher at the Calgary Herald; and Marty Klyne, publisher of the Saskatoon StarPhoenix and Regina Leader-Post will be leaving the organization.

Bill Neill, head of Postmedia's national sales operations, is also leaving the company.

Marty Beneteau, however, continues as editor-in-chief at the Windsor Star.

Postmedia has been cutting costs across its operations as part of a three-year program to transform its money-losing business.

Earlier this month, the company reported a $14.2-million loss in the second quarter due to a 10 per cent drop in revenue and losses related to currency exchange values.

At that time Postmedia president and chief executive Paul Godfrey said that the company would look at other ways to lower expenses.
