The Labour Party has appointed credit reference agency Experian to create a direct marketing campaign that will rely in part on e-mail.
The effort will reportedly see Experian create, build and manage a database of UK voters for use in permission-based e-mail and marketing campaigns.
Online research group Hitwise has been bought by Experian in a $240m (£120m) deal.
The credit information provider says it will use the acquisition to extend the range of online and offline marketing services it can offer its clients.
