A Sky News journalist accused of "faking" a television report from a British Royal Navy submarine during the Iraq war has resigned, Sky News say.
The report purported to show the preparation and firing of a cruise missile from HMS Splendid. But a BBC documentary crew filming at the same time said it had been specially staged for the benefit of Sky's camera and no missile was fired.
Sky News said James Forlong's report was unacceptable to a news operation which had built a "proud reputation for accuracy and integrity".
Forlong said: "It was, in 10 years of unblemished service with the company, a single lapse of judgement which for me is a source of deep regret.
"There was never any conscious intent to deceive the viewers, though I accept that was the outcome."
Head of Sky News Nick Pollard said he was pleased the issue had been dealt with quickly. The BBC allegations are made in a documentary "Fighting the War" which will be aired on Sunday.
A second member of staff who had also been suspended during the investigation was cleared.
Sky News is controlled by Rupert Murdoch's News Corp.
