Identity Cards Bill

I am not sure that I heard the Minister apply his mind to an issue that causes me very serious concern—the requirement under the terms of the Data Protection Act to remove data from a database as and when it becomes irrelevant. I have no idea how the Government are going to apply the criteria to that test, and I seriously would like to know. I am not suggesting that the Minister deal with it now, but if he could guarantee to write to me I would be most grateful.
