Like the right hon. Member for Blackburn, Mr Blunkett speaks from his own experience of the highly professional work of the agencies. The point he raises reinforces the importance of our agencies applying and upholding the laws of the United Kingdom regarding the data they obtain from other intelligence agencies around the world. As I said earlier to the shadow Foreign Secretary, Mr Alexander, there may well be occasions over the coming years when we will need to update and improve those procedures, to take account of changes in technology. I do not exclude that at all, but it re-emphasises the importance of applying our law in our country, which the agencies can be relied on to do.
