Various mainstream newspapers etc are faffing about with stories based on the Wikileaks published US Diplomatic Cables obtained, seemingly, from the trusted insider "whistleblower" Bradley Manning, a low level US Army intelligence analyst, with day to day access to SIPRnet, the Secret Internet Protocol Router Network, a US Military and Intelligence intranet.
Gary McKinnon was, back over 8 years ago, no doubt trying to get through to this network, which should have "air gaps" between it and the NIPREnet, the "non-classified" intranet, which at the time, had insufficient firewalls to protect it from the public internet.
The Wikileaks.org published alleged diplomatic cable is here.
The only bit about Gary McKinnon is this:

The UK on Key Issues
¶2. (S//NF) The Secretary's meetings with PM Gordon Brown and Foreign Secretary David Miliband likely will focus on the following key issues:
-- Northern Ireland
-- Nuclear Non-proliferation
- Defense Trade Treaty
-- Arms Trade Treaty
-- Gary McKinnon Extradition Case - The PM will likely raise with the Secretary (as he has with the Ambassador) the extradition case of Gary McKinnon. McKinnon is a 43-year old computer hacker with Asperger's Syndrome who is wanted for prosecution in the U.S.; he is accused of hacking into U.S. government systems in 2001 and 2002. McKinnon has gained enormous popular sympathy in his appeal against extradition; the UK's final decision is pending. The case has also caused public criticism of the U.S.-UK extradition treaty. In August, PM Brown, in a one-on-one meeting with the Ambassador, proposed a deal: that McKinnon plead guilty, make a statement of contrition, but serve any sentence of incarceration in the UK. Brown cited deep public concern that McKinnon, with his medical condition, would commit suicide or suffer injury in imprisoned in a U.S. facility. The Ambassador has raised this proposal with AG Holder and would be happy to brief the Secretary in more detail.
The (S/NF) designation of that part of the Diplomatic Cable from the US Embassy means "Secret / Not for Foreigners"
There is absolutely nothing in that paragraph which deserves a "Secret" classification, based as it is on public concerns.
