For Sale: The Details of 25 Million UK Child Benefit Claimants

I have two CD's that contain the personal details of 25 Million UK child benefit claimants.

The details include the personal information of 7.25 million claimants, 15.5 million children, including some who no longer qualify but whose family is claiming for a younger child, 2.25 million 'alternative payees' such as partners or carers, 3,000 'appointees' who claim the benefit under court instructions, 12,500 agents who claim the benefit on behalf of a third party.

I'm open to offers. How much are you prepared to pay?
