Pupils at St Matthew's Primary School in Surbiton got an unexpected treat when actor and children's author David Walliams stopped by during a break in filming a new show.

Walliams is filming an Agatha Christie adaptation in the area and was asked by the Langley Road school if he would drop by.

The Little Britain star and Britain's Got Talent host duly obliged, reading extracts from his latest book, Awful Auntie.
