Sandi Toksvig thinks that being called a National Treasure is bit embarrassing, and she has decided instead to become a National Trevor. Half misprint, half Danish comedian, novelist, actor and broadcaster Toksvig is back at Southbank Centre with a new one-woman show. Expect tall stories, fascinatingly funny facts, really silly jokes and some terrible baking from the host of The Great British Bake Off, QI and Fifteen to One. Don’t expect tap-dancing, needlework or headstands. In the quick-fire Q&A you can ask Toksvig whatever you want – but please don’t ask her bra size (she doesn’t know).
