With Mark Lawson. Novelist John Irving discusses his new book In One Person, which has, like all of his novels, been written back to front with the ending first. It's a doorstop rather than a novella, but Irving explains that when you're looking at the impact of 30 or 40 years on a life it's hard to be brief. Trade and politics forged a bond between Manchester and the countries of West Africa that dates back to the 19th century. A new citywide festival - We Face Forward: Art from West Africa Today - seeks to update that bond through contemporary art and music. Writer Jackie Kay, whose memoir exploring her Scottish and Nigerian heritage won the Scottish Book of the Year Award last year, joined Mark on the festival's art bus and took a tour round the exhibitions. British designer Thomas Heatherwick was described by Terence Conran as a "Leonardo da Vinci of our times". His range of creations includes a bridge that rolls open and closed, the new Routemaster bus, a seed-bank and the cauldron to hold the Olympic Flame. Sarah Crompton of the Daily Telegraph considers two displays of Heatherwick's work: a forthcoming exhibition at the Victoria and Albert Museum, and a new book. Producer Erin Riley.
