Fourth week at the top for Walliams, as Moyes has stellar launch

David Walliams and Tony Ross' The World's Worst Parents (HarperCollins Children's) has notched up a fourth week as the UK Official Top 50 number one, selling 22,993 copies through Nielsen BookScan's TCM.

Jojo Moyes' The Giver of Stars (Penguin) was the highest new entry, rocketing straight into the Mass-Market Fiction number one with 19,256 copies sold in its first three days on sale. It was closely followed in the Top 50 by Lucinda Riley's The Sun Sister (Pan), which hit third overall and second in the Mass-Market Fiction top 20.

Rebecca Wilson's What Mummy Makes (DK) toddled straight into the Hardback Non-fiction number one with 15,777 copies sold, following in the footprints of baby recipe book Joe Wicks' Wean in 15 (Bluebird), which hit the top spot earlier this year.

Bill Bryson's The Body (Black Swan), which sold over a quarter of a million copies in hardback, debuted in the Paperback Non-fiction number one after three days on sale. The Body elbowed out Reni Eddo-Lodge's Why I'm No Longer Talking to White People About Race (Bloomsbury), breaking the latter's seven-week run in the category chart top spot.

Chris Carter's Written in Blood (S&S) surged to the top of the Original Fiction chart, displacing David Mitchell's Utopia Avenue (Sceptre). New entries, including Shari Lapena's The End of Her (Bantam), Emma Donoghue's The Pull of the Stars (Picador) and Trisha Ashley's The Garden of Forgotten Wishes (Bantam), peppered the top 10.

Print book sales have calmed down since the first few feverish weeks of bookshops reopening, but are still comfortably up year on year. Last week, 3.3 million books were sold for £28.4m, a rise of 4.7% in volume and 7.3% in value against the same week in 2019.
