Tesco and Argos express work scheme concerns

Stores including Tesco and Argos have expressed concerns over a government work experience scheme which has been derided by critics as "slave labour".

The "sector-based work academy scheme" lets those on unemployment benefit work for a period without losing payments.

But Argos says it wants assurances that young people who do not take part will keep their benefits and Tesco has offered to pay those on placements.

However the government insists the scheme is an "excellent" opportunity.
