Cork businessman Leslie Buckley has been appointed chairman of the board of Independent News & Media at an extraordinary general meeting held in Dublin's Conrad Hotel on Monday.
The move will further consolidate the position in the company of billionaire businessman Denis O'Brien.
Buckley is the vice-chairman of international mobile phone operator Digicel and helped manage the start-up of the Esat Telecom Group and Esat Digifone with O'Brien.
Buckley was voted off the board of Ireland's largest media company last year, but since then O'Brien has increased his shareholding at INM from 22 percent to 29.9 percent.
INM publishes the Irish Independent newspaper.
