Sun reporter Harry Arnold's Hillsborough regret
Harry Arnold, the Sun journalist who wrote a story alleging drunk Liverpool fans abused victims and police during the Hillsborough disaster said he was "aghast" when he saw the headline.
Arnold told the BBC his story had been written in a "fair and balanced way" and the controversial claims had been "allegations".
He claimed it was editor Kelvin MacKenzie who wrote the headline "The Truth".
Official papers will be released on Wednesday, 23 years after the Hillsborough disaster in which 96 Liverpool fans died.
The BBC tried to contact Kelvin Mackenzie but he was unavailable for comment.
Hillsborough: Searching for The Truth is broadcast on Sunday, 9 September at 22:25BST on BBC One Yorkshire and North West, and nationwide on the iPlayer for seven days thereafter.
