GCSB investigates itself
The Government's spies are snooping on each other as the GCSB tries to find out who talked to the Labour Party.
They're not sure anyone did, but party leader David Shearer says "sources" within the Government Communications Security Bureau have told the party Prime Minister John Key's visit to the agency's headquarters in February was recorded.
Mr Shearer says the recording - if it exists - might prove Mr Key talked to staff about Kim Dotcom.
Mr Key has told Parliament he first knew of the GCSB's involvement with the internet tycoon on September 17, when the agency's chief executive Ian Fletcher told him Dotcom had been under surveillance which was later discovered to have been illegal.
Mr Fletcher said late on Thursday night "exhaustive inquiries" hadn't turned up any audio-visual recording of Mr Key's visit.
"An investigation has commenced within GCSB as to whether there has been any unauthorised disclosure of information, and if so, its source," he said.
Mr Key says he remembers talking to staff but doesn't think he mentioned Dotcom.
Mr Shearer's version of events is that Mr Key visited the GCSB on February 29 and after being briefed on its activities spoke to staff in the cafeteria.
"It (a recording) may show John Key referring to Kim Dotcom," Mr Shearer said.
"There is one way to clear this up - the prime minister should give the green light to the agency to release any and all unclassified material about the visit and John Key's comments to staff."
He told Firstline this morning "multiple sources" within the organisation had told him about the tape, and that a number of staff had it on their computers – but other staff within the GCSB wiped them.
Mr Key has told media he doesn't think there was an "official" recording of his visit, but it's possible a staff member might have one.
He says he doesn't have a problem with it being released, if it exists.
Opposition parties are calling for a commission of inquiry into the Government's involvement in the Dotcom case.
The United States is trying to extradite Dotcom so he can face copyright charges over his filesharing Megaupload website.
