Gordon Brown is joining Tim Berners-Lee on the board of directors of the World Wide Web Foundation.
The former prime minister will advise the foundation on ways to involve disadvantaged communities and global leaders in the development of sustainable programmes that connect humanity and effect positive change.
The foundation leads programmes that "empower people to use the web to nurture local economies and improve access to education and information", it says.
Gordon Brown said, "I support the Web Foundation's mission to promote the advancement of the web, as well as access to it, especially in Africa where the web can act as a catalyst for economic growth."
The foundation said its directors don't get paid for their work.
