Born the son of a Billingsgate porter at the height of the Second World War, David Jason was a reluctant electrician before finding his vocation - making people laugh - in the 1960s and 1970s. Then in 1981, kitted out with a sheepskin jacket and a clapped-out Reliant Regal, he found the part that captured the nation's Derek 'Del Boy' Trotter. Here he tells the story of life, near-death experiences and five decades as one of Britain's favourite actors.
