Ward gradually emerged as the most prominent of Seddon's supporters, and was seen as a possible successor. As Seddon's long tenure as Prime Minister continued, some suggested that Ward should challenge Seddon for the leadership, but Ward was unwilling. In 1906, Seddon unexpectedly died. Ward was in London at the time. It was generally agreed in the party that Ward would succeed him, although the return journey would take two months – William Hall-Jones became Prime Minister until Ward arrived. Ward was sworn in on 6 August 1906.
