My hon. Friend makes an interesting point. Such cases are probably down to the local authority, which can take action in the case of a local authority property, but if it is not such a property it is much more difficult. It is amazing to see what people dump in their gardens, and then the grass grows up through it and it is really unsightly; it can attract vermin and be hazardous. I will probably put myself into a minefield if I go too far down that route, buy it is essential that society behaves in a reasonable manner, so that our neighbours are able to live without unsightliness. Also, it is essential from an environmental health point of view.
