Joanna Lumley at Henley Literary Festival

Who better to celebrate the record-breaking reign of the Queen than another national treasure, keen royalist Joanna? A Queen for All Seasons: A Celebration of the One and Only Queen Elizabeth II on her Platinum Jubilee, is a collection of special writings and illuminating insights marking the monarch's unprecedented seven-decade reign, covering a period of dramatic change for the Royal Family, the country and the world. Now the Absolutely Fabulous star and Gurkha Justice campaigner comes to Henley for a special post-Festival event to discuss the book and the Queen, as well as reflecting on her own unique career, which has ranged from New Avengers in the 70s to Motherland this year. Interviewed by Good Housekeeping's editor-in-chief Gaby Huddart.
