Environment Bill

On a point of order, Madam Deputy Speaker. I am sorry to interrupt this debate, but colleagues may or may not be aware that, this week of all weeks, there is now a demonstration in Parliament Square involving Piers Corbyn. The people there have erected a gallows—gallows to be used against Members of Parliament. I would suggest that at the very least it is not only crass and unthinking, but that it must also be a breach of public order. I simply rise to ask whether there is anything that can be done about it.
