A partnership between Tesco and the Government-backed National Saving & Investments has ended just one-year into what was believed to be a five-year deal following disappointing sales.

The project allowing shoppers to pick up brochures for Premium Bonds and other NS&I products in Tesco stores and then buy via a link on the supermarket group’s website ended in April without a public announcement.

The scheme was launched in March 2006 after a four-month pilot scheme 50 Tesco stores. A spokesman for Tesco said the project had ended by mutual agreement.
