May I associate myself with the Prime Minister’s words and those of my right hon. Friend the Leader of the Opposition? Does the Prime Minister accept that this is not about our personal security, as Members of Parliament, or about the security of this building? PC Keith Palmer died defending the values of, as the Prime Minister put it, “free people everywhere”. Is not the proper response over the coming days, as more facts emerge, to stand firm for those self-same values of free people everywhere?
