An Andover primary school has featured in a national World Book Day assembly where they quizzed David Walliams on his writing. The pupils of Endeavour Primary School asked the comedian and children’s author on the inspiration for his books, with Walliams revealing he had based one character, Blubbering Bertha, on his own sister! The school said that the assembly was an “amazing part of World Book Day” and was delighted to take part. The Amaaaaazing Assembly was set up by publishers HarperCollins, who publish classic childrens’ books including The Tiger Who Came to Tea and A Bear Called Paddington as well as those of David Walliams.
