A new campaign has been launched on World Book Day that aims to greatly increase the number of books made available to blind and partially sighted people.

The RNIB says more than 95 per cent of books that are published never become available in large print, audio or braille.

The charity hopes its Talking Books campaign will tackle a problem for blind people in Britain that it calls 'unacceptable'.

The RNIB is collecting donations from the public to spend on making more titles avaliable, especially children's stories.

The campaign has the backing of celebrities, including the writer Julian Fellowes and TV presenter Ian Hislop.

There are almost two million people living in the UK with sight loss.
