Among several allegations are that, as summarized by the BBC:
The Mail on Sunday claims Libyan spies working on UK soil were supplied with intelligence, a luxury safe house in Knightsbridge, west London, and secure mobile phones. The paper says MI5 "betrayed the confidentiality that refugess are promised when they apply for asylum", citing documents "unearthed from Libyan spymasters' archives" after the Gaddafi regime was toppled last year.
A Home Office spokeswoman said the department did not comment on operational matters because of safety issues. . . . But she added that parliament's Intelligence and Security Committee was already looking into the government's relationship with Libya "and will take account o any allegations raised by this report."Previous coverage of the captured Libyan documents available here, here, and here.
