My hon. Friend sums up one of those lessons well. It is important that, taking from what has happened here, we understand that system changes need to be made, and behavioural and cultural changes need to take place, some of which, in my view, are well under way. However, none of us should be complacent about them and we should all be vigilant to ensure that we continue to apply our values. My hon. Friend is right, too, that if we allow our values to erode, then so shall our influence around the world.
