My Lords, that has been a very helpful debate and I thank all noble Lords who have taken part. My noble friend Lady Morris suggested that some of us might have taken part in heckling in the past. I have to confess that I took part in one of the first university sit-ins at Leeds University in 1968, when—led by one Jack Straw, who was then president of the Leeds University union—we heckled Mr Patrick Wall, an MP at the time.
The noble Lord, Lord Grabiner, made a very important point about drawing the distinction between quite legitimate heckling and the kind of intimidatory action that we saw taking place in relation to a number of women academics. The noble Lord, Lord Macdonald, is absolutely right: I agree that there are elements of criminal behaviour. The problem is that universities were very weak. I really regret that the Bill has been necessary, but I am afraid that the lack of backbone shown by so many university leaders is why we are here today.
I agree with noble Lords that this is not a matter for primary legislation. Indeed, I am not quite sure how you would ever draft anything like it. We tried in Committee but I think one has to accept that it is not possible. The codes of practice and the oversight of OfS, though, are clearly crucial to the success of this legislation, so this has been a very good debate.
In relation to Amendment 16, I very much hope that the OfS will take note that any guidance it issues needs to be fully understandable by students within the student union. Having said that, I beg leave to withdraw my amendment.
