I am grateful to the right hon. Gentleman for his question, and I pay tribute to him for his service as Secretary of State. He is absolutely right that the report makes it quite clear that there were omissions, and that if the Northern Ireland Office or the RUC had done certain things, the risk would have been reduced. However, it was also incumbent on Mrs Nelson to accept security advice at the time and ask for security help. I made it clear in my statement that I regret that those omissions meant that the risk was not reduced, but we have to face the fact that under the circumstances, it was impossible to eliminate the risk.
