I thank the Chairman of the Communities and Local Government Committee for raising that point. As well as writing to local authorities, I will write to a number of other organisations, including civil society bodies, in looking for ideas on how to tackle this issue. I said in my statement that we will look at public databases. Other issues arise if we want to look at private databases, but we are considering that too as we want to use a wide variety of sources. As I will be writing to local authorities, I urge hon. Members who are concerned about registration to speak to their local authorities and to encourage them to participate in those pilots. We want a wide range of authorities to take part, and we want to look at a range of data sources because we want to discover which of them are the most effective before we roll this out across the country.
