Glenn Greenwald, the Brazil-based reporter who broke the NSA surveillance scandal, has announced he is leaving The Guardian.
Mr Greenwald thanked his editors and colleagues for their continued support during his tenure at The Guardian.
Although details are not yet available of his new venture, he explained that it is a "once in a lifetime opportunity" for any journalist.
"My partnership with the Guardian has been extremely fruitful and fulfilling," he said in a statement released today, after the news was leaked early.
"I have high regard for the editors and journalists with whom I worked and am incredibly proud of what we achieved.
"The decision to leave was not an easy one, but I was presented with a once-in-a-career dream journalistic opportunity that no journalist could possibly decline.
"Because this news leaked before we were prepared to announce it, I’m not yet able to provide any details of this momentous new venture, but it will be unveiled very shortly," he concluded.
Mr Greenwald said yesterday that there any more stories from Edward Snowden's leaks that will soon be published.
