Footage of the argument between Mr Sweeney and Mr Davis was posted on internet site YouTube.
Reflecting back on the controversy, John Sweeney says: “I apologised then and I apologise now. It was wrong and I’d let my team down.
“Unsurprisingly Scientology used their recording of my meltdown against me.
“They compared me to Hitler, accused us of faking evidence and being linked to terrorism – charges we deny by the way.
“Then I went global. My rage spread like a computer virus across the world. Scientology moved the battle to the internet.
“They posted their recording of my meltdown. We fired back showing the context and reporting what Scientology’s critics say: that it’s a cult.
“And so it spreads, jumping oceans and time zones: two million hits on YouTube and counting.
“A new generation is making up its own mind about Scientology. And for that I make no apology.”
