The publisher of the Yorkshire Post faces a power struggle with the horse racing tycoon

In an update to the stock exchange this morning, Media Concierge said it approached the board with its offer 22 days ago but had received “no substantial engagement”.

It urged National World to consider the offer of 21p per share, which represents a 40% premium to the company’s closing price on Thursday.

Media Concierge said the offer provided “a very attractive and deliverable opportunity for National World shareholders to realize their investment at a substantial cash premium”.

Mr Denmark is understood to be frustrated by the lack of direction at National World, as well as its digital strategy. The publisher said it will produce half of its newspapers using artificial intelligence by the end of the year.

Mr. Montgomery, 76, is known for cutting costs significantly on his titles. National World has cut more than one in four jobs since it bought more than a dozen titles from collapsed publisher JPI Media in 2021.

Mr. Denmark started his business in 1985 with the launch of an advertising agency representing media owners. It has since expanded its interests and is Ireland’s largest regional newspaper publisher with 22 titles.

The 69-year-old is also a prominent racehorse owner, competing in both England and Ireland. Not a gambler, he has previously criticized bookmakers’ relationship with the sport.

A spokesman for National World declined to comment.
