Former prime minister Tony Blair yesterday made his long-awaited appearance at the Chilcot inquiry into the Iraq invasion. He made clear that he did not regret his decision to go to war and that the decision was not made on lies or deceit.

Mr Blair's evidence followed a week of revelations after top foreign office lawyers Michael Wood and Elizabeth Wilmshurst declared the war illegal, and the former attorney General Lord Goldsmith explained the change in his own advice on the legality of the war.

Political correspondent Norman Smith outlines the reaction to Mr Blair's evidence, and Peter Hennessy, historian and Attlee Professor at Queen Mary University, London, analyses the week's revelations.
