Computer hacker Gary McKinnon will face no further criminal action, the Director of Public Prosecutions, Keir Starmer QC, has said.
The decision follows a review of the case after the Government's decision to block his extradition to the United States in October on health grounds.
Mr McKinnon, 46, from Wood Green, north London, would have faced up to 60 years in prison if convicted in the US.
