As the summit began the world's leaders professed their determination not to be intimidated but to carry on meeting. Mr Blair insisted that "the issues we are discussing are, in fact, the very issues that some of those people say they are protesting about". But that was before the news arrived of the death, after which the Prime Minister's spokesman adopted a different tone, arguing that it is "always a source of regret if anyone loses their life. We have always defended people's right to legitimate and peaceful protest, but when there is violent protest people can get hurt."
