HARRY POTTER

» Harry Potter continues to conjure up magic for publisher Bloomsbury.

The 20th anniversary of JK Rowling’s first episode helped lift sales of the boy wizard’s adventures by 5% in the six months to September.

Excluding this, children’s book sales were down 9%. But total half-year revenue rose 4% to £75million, with profit up 13% to £2.9m.

Bloomsbury has lined up a raft of new titles, including from top chef Tom Kerridge.
