His international career opened for Great Britain in 1967. The following year he played three World Cup matches, grabbing a hat-trick against New Zealand. In 1970, he toured Australasia, but only participated in one test due to injury. He however won a further three test caps against New Zealand in 1971. In 1972 he was handed the captaincy of Great Britain, and played two tests against France. The World Cup took place that same year, and he captained Great Britain to become world champions. He scored a try in each of Great Britain's four games and scored a try to level 10–10 against Australia in the World Cup Final, after a length of the field run.
