Reda Hassaine, an Algerian informer working for the Metropolitan Police’s Special Branch against Islamist extremists in London, is passed to MI5, Britain’s domestic intelligence service. One of his tasks is to identify men who attend Finsbury Park mosque, a hotbed of radicalism, in photographs MI5 gives him. For the first six-month trial period, Hassaine is given £300 (equivalent of $450) per month plus £80 for expenses, but MI5 tells him to claim unemployment and housing benefit as well, “because, after all, we were dealing with the security of the country,” and “it would be a good cover story because everyone in Finsbury Park was foreign and on benefits.” In return for his work, Hassaine is promised he will obtain indefinite leave to remain in Britain, but in February 2000 he will only receive leave to remain for four years, which he will be unhappy about.
