Parliamentary Voting System and Constituencies Bill

I hesitate because I do not want to say anything definite if there are data protection problems, but that is a positive suggestion and one that I will no doubt look at to see if it can be done. The noble Lord is absolutely right. It is one possible way and if it can legitimately be done I am sure that it will help. The pilots will be tried later this year. The precise locations have yet to be confirmed, but a report will be published by the Electoral Commission towards the end of the year. When pilots have been run, it will be possible to broaden the scope. This is not an either/or. It is important that we do this. However, if we were to proceed with the amendment, not only is it possible that one or two councils would not be certified by the Electoral Commission before the 2025 election, but even on the basis of the 2015 election we would still be using data for England that would be 15 years old. If there are 3.5 million people missing, I suspect that the data for 2000 are even more damaging. There is a difference between the data that are used for calculating the numbers for the constituencies and the important objective year in, year out to make sure that the electoral roll is as up to date as possible and that people are on it who ought to be on it.
