The Week: City news - O'Brien raises IN&M stake

Denis O'Brien, the Irish media tycoon, has increased his stake in Independent News & Media, the publisher of The Independent and Independent on Sunday, from 18.05 per cent to 19.35 per cent.

O'Brien, who has been building up his holding since April last year, is openly critical of Sir Anthony O'Reilly, IN&M's chief executive and largest shareholder. O'Brien has called for the company to sell off its loss-making flagship national newspaper titles.
