Britain's MI5 Infiltrated by al-Qaeda?
In a rush to recruit informants after the 7/7 bombings in 2005, it appears that Britain's MI5 was infiltrated by al-Qaeda operatives posing as informants.
Bosses at M15 believe they unwittingly recruited the Muslim extremists after the July 7 suicide bombings in London last year which killed 52 people.
They were signed up as part of a drive to find more Muslims and Arabic speakers to work as spies to help prevent future attacks by Osama bin Laden fantatics.
Spymasters found some of the agents in Britain's universities and colleges and persuaded them to pass on information about suspected terrorists.
But a senior ministerial source has told the Sunday Mirror: "The truth is that it has now been discovered that some of those people have strong links with al-Qaeda.
"There was always a risk that with such a speedy and widespread recruitment some would turn out to be bad eggs."
Such is the nature of the intelligence business. For as long as there have been intelligence operations, there have been counter-intelligence operations.
