My Lords, I speak as a member of the Joint Committee on Security, which has been looking at this for years and has got nowhere. At our last meeting, we were told something quite extraordinary; namely, that although what surrounds the square may look like a pavement and, if you fell on it, would feel like a pavement, the High Court has announced that, as it does not go anywhere, is not a pavement-which shows the idiocy of judges. That is one of the things that prevents anyone, including the Met, from doing anything about these squatters.
