Sources close to the company say that as many as 200 marketing jobs out of a total of around 400 will eventually be culled. But the cutbacks are likely to be introduced in phases and the final figure has yet to be determined.
Around 150 of the losses will come from the Royal Mail division, with 50 from the Post Office.
Royal Mail is merging its business and consumer markets (BCM), media markets (MM) and e-enterprise units to form a single mail division. Last week, Marketing revealed that BCM managing director Gillian Wilmot was leaving the company, while internal candidate Paul Rich was the surprise choice to become group marketing director.
It has since emerged that Rich will also take on the title of deputy managing director and become Royal Mail's first executive board-level marketer. Rich will report to group managing director Jerry Cope when he takes up the dual role in January.
Future roles have still to be announced for brand and communications director Paul Troy and MM managing director Adam Novak, though sources say that both men are to be offered senior roles. Neither could be contacted as Marketing went to press.
The restructure comes as Royal Mail Group faces up to losses of 拢1m a day, a decline that will be accelerated by the opening of the postal market to competition and the automation of benefit payments directly into bank accounts.
Post Office chief executive David Mills last week told a House of Commons Select Committee that government interference was hindering plans to market the new Post Office Card Account, due to launch next year.
