In 1975, he won four fights in a row, including another bout in Hamburg and, by the end of the year, he challenged Kevin Finnegan for the British Middleweight title, winning it by a 15-round decision. In 1976 he won six fights, to extend his streak to ten consecutive wins. Among the boxers he beat were Billy Knight by a knockout in two and Finnegan once again, by decision in 15, both in defence of his British title, along with former world title challenger Tony Licata, knocked out in six and American Olympic Games Gold medal winner Sugar Ray Seales, beaten in five. These wins gave Minter a ranking among the top ten Middleweight challengers.
