Hawke resigned as President of the Labor Party in August 1978. Neil Batt was elected in his place. The strain of this period took its toll on Hawke and in 1979 he suffered a physical collapse. This shock led Hawke to publicly announce his alcoholism in a television interview, and that he would make a concerted—and ultimately successful—effort to overcome it. He was helped through this period by the relationship that he had established with writer Blanche d'Alpuget, who, in 1982, published a biography of Hawke. His popularity with the public was, if anything, enhanced by this period of rehabilitation, and opinion polling suggested that he was a more popular public figure than either Labor Leader Bill Hayden or Liberal Prime Minister Malcolm Fraser.
