Yes. My hon. Friend is quite right: it is incumbent on political leaders, from whom many other members of the community take their lead, to act immediately, not just when antisemitism gets exposed in the media or when pressure builds, and not because it is convenient but because it is right. Whether it is the example in Harrogate that my hon. Friend gave or, indeed, the recent example in Rochdale, acting immediately from principle is what counts, not just reacting to public pressure a few days later.
