During the Conservative Party Conference in Manchester an enterprising Buckinghamshire company ran a social enterprise project.

Calibre Audio Library, based in Aylesbury, provides a free audio book service for the visually impaired.

It set up special booths for MPs to record chapters of an audio book of children's stories, and even got Prime Minister David Cameron and his wife Samantha to take part.

The prime minister read Hamish Goes Swimming in Funny Stories for Eight Year Olds.

Samantha Cameron read Emily's Legs.

Only 5% of books in this country are available in accessible format, and the library relies on a team of volunteer readers.

This week the final product was released, and there are some great performances!

MPs' star turns

David Lidington does a great line in blood curdling chill for a horror story about the night that death came to collect the blacksmith's daughter.

Nicola Blackwood puts her singing background to good use with a more gentle story.

The two books, which are free for Calibre's 19,000 members to borrow, are available as Christmas presents from its website

Education Secretary Michael Gove had a morality tale, and made sure his grammar and pronunciation was beyond reproach.

And the two star turns are well worth a spin.

Take a listen to David Cameron and his wife Samantha in the excerpts on this page.
