Sonia Purnell is a journalist and bestselling author known for her lively writing style and meticulous research with a growing readership across the world. Her first book - the unauthorised biography of Boris Johnson called 'Just Boris: A Tale of Blond Ambition' - was long listed for the Orwell prize in 2011. Her second book, 'First Lady' in the UK and 'Clementine' in the US, (a finalist for the Plutarch prize) revealed for the first time the vital role played in Winston Churchill's career by his wife Clementine and has been optioned to be made into a Hollywood movie. Her new work, 'A Woman of No Importance', is the astonishing but true-life tale of a female spy in WWII, Virginia Hall, a young American socialite with a wooden leg, who helped fan the flames of French Resistance. It will be published in March in the UK and elsewhere in April and the rights have already been sold to Paramount for a major film starring Daisy Ridley.

Sonia is also a highly popular speaker and broadcaster and is preparing to give interviews to a wide range of media in both Britain and the US on her her forthcoming book, A Woman of No Importance. As well as also appearing in a number of literary festivals in the UK, she will be touring the United States for two weeks this April. Tickets will be available soon. All further inquiries should go to her publicist Grace Vincent in London or Rebecca Marsh in New York or her agent Grainne Fox.

Sonia Purnell's work is 'brilliant' (The Independent), and 'indispensable' (The Guardian) because 'she dares to speak truth unto power'. The Wall Street Journal described her biography of Clementine Churchill as 'a fine book' and an 'astute and pacey' account, while the New York Times described her work as 'engrossing' and the Daily Telegraph as 'admirable'.

She has written for most national newspapers in the UK, several prestigious publications in other countries including the Wall Street Journal in the US, and lives in London with her husband and two sons.
