The Mirror has signed up as a media partner for the campaign, which begins next year, and will run a scheme offering children a week of free school dinners via tokens in the Daily and Sunday Mirror newspapers. It will back the drive with editorial.
The deal with The Mirror was negotiated by Golley Slater Promote.
The trust, which was set up in 2005 by the Department for Education and Skills, now the Department of Children, Schools and Family, aims to improve the quality of school meals and to encourage more children to eat them.
