Prime Minister John Key mounted a fierce defence of the GCSB spy agency yesterday and accused Labour leader David Shearer of besmirching the integrity of chief executive Ian Fletcher.
Mr Key said Mr Shearer accused the GCSB of engaging in "Watergate-type activity" by suggesting it had deleted a recording of a speech Mr Key gave on February 29.
"That is utterly refuted. I have been advised by the director that there was no video, that there never was a video, and that nothing has been deleted from the Government Communications Security Bureau's system."
Mr Key's defence of the agency contrasts with his disappointment at it last month when he was forced to apologise to Kim Dotcom for illegal spying.
The Prime Minister was further embarrassed by revelations that the agency had mentioned Mr Dotcom to Mr Key on February 29, contrary to his earlier recollections.
