North's impressive return to form following his move back to Wales meant that he was an automatic choice for Wales' 2019 Six Nations Championship squad, and the starting XV against France. Despite a sloppy first half performance that allowed Yoann Huget to score in the left corner, North gave one of his best recent performances in the second half, scoring two tries and winning the Man of the Match award. North became a grand slam champion for the second time in his career, in the 2019 Six Nations, as they beat Ireland 25-7 in Cardiff.
