U.K. Government Insists Guardian's NSA Data Posed "Threat to National Security"

Even though destroying hard drives didn't destroy the widely disseminated data

Nick Clegg has endorsed the government's decision to ask the Guardian to destroy leaked secret NSA documents on the grounds that Britain would face a "serious threat to national security" if they reached the "wrong hands".

In a statement, a spokesman for the deputy prime minister gave the first official confirmation that the cabinet secretary, Sir Jeremy Heywood, made the request to the Guardian.

The intervention by Clegg came after Yvette Cooper said that parliament's intelligence watchdog should investigate David Cameron's role in asking the Guardian to surrender or destroy the NSA documents. The shadow home secretary made her call after the Daily Mail and the Independent reported that Heywood made the request to the Guardian on the instructions of the prime minister.
