A source, not from Whitehall but with knowledge of the payments, said: "It's been driven by the [intelligence] agencies, it's a network of human resources across the country engaged to effectively spy on specific targets. It's decent money." They did not divulge the number of informants receiving funding or how much of the agency's budget was devoted to it.
The use of payments to gather information prompted calls for caution from senior figures in the Muslim community, who warned that they could produce tainted intelligence.
Salman Farsi, spokesman for the East London Mosque, the largest in Britain, said: "We want our national security protected but, as with everything, there needs to be due scrutiny and we need to ensure things are done properly.
"If there's money on the table, where's the scrutiny or the oversight to ensure whether someone has not just come up with some fabricated information? Money can corrupt."
Farsi said the Government's central counter-radicalisation programme, Prevent, had seen tens of millions of pounds spent but faced criticism for failing to achieve its goals.
