A fresh legal bid to throw out the case against Kim Dotcom in the United States is being made after claims of an FBI double-cross.

The Kim Dotcom case threatens to pull New Zealand's most secretive spy agency into court in a bid which could probe intelligence links with the United States.

Prime Minister John Key says an accusation that he lied about the extent of his knowledge of internet tycoon Kim Dotcom is "just plain wrong".

Foreign Affairs Minister Murray McCully was briefed on the need to seize Kim Dotcom's assets at the time his officials were worried rejecting requests might upset the US.

Kim Dotcom claims he has proof that Prime Minister John Key lied about not knowing who the Megaupload millionaire was until just before the raid on his Coatesville mansion.

A central African country has suspended Internet entrepreneur Kim Dotcom's new website domain www.me.ga.

The "Mega" business has been forecast as a replacement for Megaupload, which was shut down in January.

The Security Intelligence Service has confirmed its investigation into Kim Dotcom found he posed no security risk to New Zealand.

Senior police have launched an investigation into the Government Communications Security Bureau's illegal spying on Megaupload millionaire Kim Dotcom, the Green Party says.

Matt McCarten looks at the line between those employed as public servants and their accountabilities.

Kim Dotcom has held the first party at his mansion since his arrest, telling 100 entrepreneurs that the case against him was hurting New Zealand's economic success.

Senior lawyer Stuart Grieve QC has been given security clearance and appointed to the Kim Dotcom case.

The saga of the Ministry of Social Development's failings certainly drew attention away from that ugly wart of what John Key knew and when about Kim Dotcom, writes Claire Trevett.

John Key has corrected statements he made in Parliament about when he was first told about the Dotcom case by the Government Communications Security Bureau.

Prime Minister John Key will this afternoon correct the answers he gave two weeks ago to questions about what he was told about Kim Dotcom by the GCSB.

Our hopeless GCSB spy service are absolutely culpable for turning a simple exercise into a farce, writes Bob Jones.

Labour leader David Shearer must be wishing he had never mentioned a recording of a remark the PM is said to have made to staff at the GCSB.

John Key has challenged Labour leader David Shearer over claims there is a tape of the Prime Minister discussing Dotcom on a visit to the Government Communications Security Bureau (GCSB) months before Mr Key originally claimed to know the agency was linked to the Dotcom case.
