The subsequent United Alternative initiative was aided by the departure of Jean Charest from the leadership of the federal Progressive Conservatives to pursue provincial politics in Quebec and by the support of provincial Progressive Conservative premiers, in particular, Mike Harris of Ontario, Gary Filmon of Manitoba, and Ralph Klein in Alberta. The process for achieving it, under Manning's leadership, was incremental, beginning with the creation of a United Alternative Steering Committee involving representatives of both parties and the convening of an initial United Alternative Conference. The Conference was held in February 1999, and attended by 1,500 delegates including both Reform and PC representatives.
