 The Witches went on to become a dominant force in the top flight of British speedway, winning the British League Championship in 1975, 1976 and 1984, plus four Knock-Out Cup wins (doing "the double" in 1976 and 1984).Following the death of Ipswich rider Billy Sanders in 1985 and Berry's subsequent decision to quit, the club struggled and almost closed before being saved by a consortium which included former rider John Louis.The new Witches began competing in the National League (second tier) in 1989 and 1990, before joining the amalgamated British League and then, after a further restructuring of speedway in Britain, the Elite League.
