The mother of Gary McKinnon has spoken of the “nightmare world” her son lives in, as she issued a renewed appeal to MPs to save him from extradition to America.

Mr KcKinnon, who has Asperger’s Syndrome, lived in Muswell Hill when he hacked into secret Nasa and Pentagon files in 2002.

He now faces up to 70 years in jail if the American authorities charge him.

Speaking on the eve of Mr McKinnon’s 46th birthday, his mother Janis said: “Ten years have gone by and still Gary lives in a nightmare world – unable to control the terror that consumes his every waking moment.

“This endless pressure on an Aspergic man with severe mental health issues is barbaric.”
