MI6 spy Gareth Williams hacked into restricted information about former US President Bill Clinton, it has been claimed.
The 31-year-old codebreaker was discovered inside a padlocked bag in a bathtub at his London home in 2010, sparking a real-life mystery worthy of any 007 thriller.
Theories about the maths genius with a taste for cross-dressing included that he was killed by foreign spooks, eliminated by fellow agents and suffocated when a sex game went disastrously wrong.
Now it is claimed he illegally obtained a guest list for an event attended by Mr Clinton as a favour for a friend who was going.
A source told the Sun on Sunday: “The Clinton diary hack came at a time when Williams’s work with America was of the most sensitive nature.
“It was a diplomatic nightmare for Sir John Sawers, the new director of MI6 at the time.”
