In addition, the results were combined with those of the previous season's championship to form qualifying Group 8 for the 1968 European Championship.
The tournament was a single round-robin with two points for a win and no ranking tiebreakers like goal difference.
England won their first two games, against Wales and Ireland, and going into the final match they were guaranteed at least a share of the Home Championship, but a win for Scotland would see them win the Euro qualifying group.
A hard-fought draw gave both titles outright to England.
Ireland had surprisingly beat Scotland, but shared third place with Wales after losing to them in the last match.
