I will have to come back to the noble Lord on that in more detail. The point he made earlier concerns me. The potential for a bundle of ballot packs to be collected up and put through a door or letterbox is something that we really need to look at. I will take it away and look at it in more detail, and I will certainly come back to the noble Lord.
The noble Lord, Lord Scriven, is pursuing a key point. It has been the case in certain investigations that fingerprinting has been used to establish who has handled the ballot papers, which would cover an element of the aspects to which he referred but not necessarily all of them.
That is true. I know there is one example in the Pickles review that I was on the ground for: in Bradford, at the 2005 general election. I think I am right in saying that it was not just fingerprints but analysis of signatures. The police were able to identify and take action because the individuals who were filling in the ballot papers did them on top of each other. It was not just the signatures they could identify; they could identify them on every single one, which enabled them to prosecute. I saw that up close several years ago.
To close this discussion, I know that all noble Lords believe that preserving our democratic processes is paramount. I will certainly come back on the very important points raised, but I am pleased to be able to introduce these measures.
