According to a market source, the acquisition was estimated to be worth over 20 million euro, or US $38.8 million.

"The paper is one of Ireland's oldest and leading regional titles and would be a good addition to our portfolio of Irish regional titles," said Vincent Crowley, chief executive of Independent News & Media Ireland, in a statement.

Independent News said the deal was subject to due diligence and regulatory approval.

Additionally, Chief Executive Anthony O'Reilly announced last week he had raised his personal holding stake in the publishing group to 26.50 percent.

O'Reilly said he had purchased one million shares, or 0.12 percent of the total at 2.3255 euro per share, nzherald.co.nz reported.

O'Reilly, his family and associates totally control around 28 percent of the group.

Irish telecoms guru Denis O'Brien has also been building up his stake in Independent News in recent months. He holds a 14.5 percent stake, making him the second biggest shareholder of this group.
