Idris Elba has partnered with Project Literacy to front a new campaign, IlliteraCity, highlighting the struggles associated with adult illiteracy.

The Luther star posted a clip from the campaign on Instagram, captioned 'I am working with @projectliteracy to launch #IlliteraCity - an imagined reality of what a city would look like if all residents were illiterate. Visit the interactive city and find out how you can build brighter futures for the 750m people in the world who cannot read and write'.
