Presenter Mariella Frostrup is the voice of a new fundraising campaign from the National Literacy Trust.
Frostrup narrates a film telling the story of eight-year-old Mia, whose family are illiterate but who learns to read through the help of NLT. The film for Mia's Campaign can be seen at www.literacytrust.org.uk.
Mia's Campaign asks members of the public to donate to help disadvantaged children and young people. The NTL currently works with 38,000 children each year, providing books, storytelling events, workshops and one-to-one support.
NLT director Jonathan Douglas said: "We know that if you can read, you can succeed. We want the public to help us give more children like Mia a route out of poverty...At this time of unprecedented economic hardship, our charity's work has never been so necessary."
The campaign is being launched to celebrate NLT's 20th anniversary. Further activities will include a Where's Wally? fun run, to be held in March.
Authors Antony Beevor, Malorie Blackman, Lauren Child, Cressida Cowell, Charlie Higson, Anthony Horowitz, Ruth Rendell, Axel Scheffler and Joanna Trollope are also involved as ambassadors for the charity in its 20th anniversary year.
