The Post has been steadily building a base in North Wales, which has seen it rival the Western Mail for a claim to be Wales’s national newspaper.
Both morning papers are owned by Trinity Mirror, which has long recognised the difficulties of distribution of the Cardiff-based Western Mail in North Wales.
The Post’s North Wales circulation is 42,561, two-thirds of the total sales of 63,215.
Daily Post editor Alastair Machray, who has edited the title since May 1995, has been promoted to editor-in-chief, North Wales, based at Llandudno Junction. He will lead a relaunch of the Welsh Daily Post, planned for spring.
An editor for the Liverpool-based English Daily Post is now being recruited. Jane Wolstenholme, assistant editor of the Post’s sister paper, the Liverpool Echo, has been made acting editor.
Mark Dickinson, who has been given the title of regional editor-in-chief, while continuing to edit the Liverpool Echo, said: "The Post is entering an exciting new phase of its illustrious history and we are seeking a high-flyer to shape its future in England.
"We plan a major development of the English title, building on the Post’s proud record."
The changes are part of a major reorganisation of Trinity Mirror’s businesses in the North West and North Wales.
The new strategy will unite the Liverpool Daily Post and Echo and Chester Chronicle and Associated Newspapers, for the three main marketplaces of Cheshire, Merseyside and North Wales.
Trinity Mirror expects improved business performance through centralised support functions.
Dickinson will represent editorial on a new regional board. Eric Langton becomes editor-in-chief, Cheshire, and will also edit the Chester Chronicle.
Chris Walker, managing editor of the Liverpool company, has been made regional managing editor, while Jane Daly extends her responsibilities as group editor for all weekly Merseyside titles. A North Wales weeklies editor will be recruited.
In addition, a new regional business development unit will look for new commercial opportunities in niche publishing and events and exhibitions.
John Bills, northwest regional managing director, said the changes had been implemented for sound commercial reasons arising from Trinity Mirror’s recent regionals exercise, "From Biggest to Best".
"The initiative will streamline our business performance to deliver savings and create opportunities for growth," he said.
