'Lost' Enid Blyton book discovered

An unpublished and previously unknown Enid Blyton novel is believed to have turned up in an archive of the late children's author's work.

Mr Tumpy's Caravan is a 180-page fantasy story about a magical caravan.

It was in a collection of manuscripts that was auctioned by the family of Blyton's eldest daughter in September.

Will Gompertz reports.
