Northcliffe, the regional newspaper arm of the Daily Mail & General Trust (DMGT), could see private equity interest. Analysts have said Candover, KKR, Apax and CVC as potential players in the £1.5bn auction of the titles. However if a rival was to step in and move on all the titles up for sale, it would likely face complex regulatory hurdles.DMGT said that Greenhill would advise on the review of the holdings. Northcliffe includes about 100 titles.
