The editor of the Irish Daily Star newspaper has resigned in the wake of the controversial publication of topless photographs of the Duchess of Cambridge.
Michael O'Kane had been suspended from his role in September while an internal investigation was carried out into the tabloid's decision to rerun pictures of Kate and Prince William sunbathing on a private holiday in France.
British media tycoon Richard Desmond, whose Northern and Shell group co-owns the newspaper with Irish-based Independent News and Media, had threatened to shut the Dublin operation down.
However, sources said shareholders were working to secure the future of the newspaper, which employs about 120 people.
It is understood there has been no change to the status of the 25-year-old joint venture on the back of Mr O'Kane's resignation.
One source said there would be "further changes", which have still to be agreed and would be announced in the future. Another said there was no momentum behind calls to close the newspaper.
In September, Mr Desmond said he was very angry at the decision to publish the photographs and was "taking immediate steps to close down the joint venture".
In a statement, the Irish Daily Star said: "As a result of the publication on 15 September 2012, issues arose with the shareholders of Independent Star Limited. Having considered those issues in tandem with Mr O'Kane, it is Mr O'Kane's decision to resign as editor of the Irish Daily Star, effective immediately."
Independent News and Media said Mr O'Kane acted at all times in a highly professional and appropriate manner and in the best interests of the newspaper.
Furthermore, he followed all editorial policies and guidelines, the statement said. It is understood the investigation into the publication of the photographs is ongoing.
