Anita Roddick is happy to tub-thump on social causes and is an open book about her family, her upbringing and her off-the-wall outlook on life.
But the 57-year-old entrepreneur is stopped in her tracks, when asked about recent revelations concerning her husband's alleged affair with a much younger woman.
