Shadow Attorney-General Mark Dreyfus said confidence in the independence of the police had been undermined following a raid last night on the Melbourne office of Labor Senator Stephen Conroy. \u201cWe\u2026need to be concerned about the appearance of police work. We need to be concerned about building confidence in our police and our agencies and for this raid to have been conducted, for the NBN Co to have pressed for an investigation and it to be brought in, in the way it which it has during an election campaign, that raises questions. It does undermine confidence in the independence of the police,\u201d he told ABC Radio National. Meanwhile, Australian Federal Police commissioner Andrew Colvin strongly denied suggestions of any political involvement in the raids, which relate to leaked internal documents from the NBN. \u201cLet me say up front for the record, the AFP always acts independently and within the law,\u201d Colvin said. \u201cIn regard to government and political influence that has been commented on this morning there has been ... no influence on the AFP in the conduct of this investigation.\u201d He said the timing of the raids, which has been called into question by opposition figures, was \u201cdetermined by the investigation\u201d. Parliamentary privilege The Labor Party has since claimed parliamentary privilege on the seized documents, meaning the AFP no longer have access to them. Colvin confirmed that the documents have now been sealed. \u201cThey will be lodged in the Senate and a process will be put into play by the parliament to determine if parliamentary privilege is afforded to those documents,\u201d Colvin said. \u201cIt is not necessarily the case that parliamentary privilege will be afforded to those documents.\u201d As parliament has dissolved until after the election in July, the AFP will have to wait for the matter can be decided, he said.
