I am pleased to say that, so far, the stream of reports has been reassuring. Clearly, we will respond if there are any signs that there is going to be an overrun, but at present I have no reason to suspect that. I have spoken of the foreign challenges, and I will now deal with the domestic challenges with which the agencies deal. The threats to our national security do not come only from other Governments. The danger to the life and safety of British citizens is more likely, in practice, to come from terrorist groups.
Terrorist outrages command massive media coverage when they happen.
Successes in preventing such outrages get nothing like the same coverage, but that does not make the crucial role of the agencies in preventing terrorism any less valuable. Since the Committee's report was published, the security services have twice participated in operations that led to the arrest of individuals who have since been charged with terrorist offences or conspiracy to cause explosions. Some of the domestic challenges are new. They reflect the nature of the modern world. The revolution in communications technology is creating new opportunities on an exponential scale.
