Sue Perkins is a bundle of nervous energy as she paces the floor of her north London flat, making coffee while we talk. We're in her cosy living room and her beagle puppy, Pickles, is bouncing around, glad to have her home after she spent just over a week in the Celebrity Big Brother house. The programme ended last Friday, with former Take That star Mark Owen emerging as the winner. Over the past few days, Sue has been getting back to normal, catching up with family and friends. But what had seemed like an interesting diversion - Perkins says she went into the house because she thought her life was "becoming boring and predictable" - has turned sour. She is feeling, to be frank, rather hacked off.
