On March 31, 2006, Premier Klein faced a mandatory leadership review when party delegates voted on the question of whether he should continue as leader of the party and, by extension, as premier. Although Klein was not widely expected to lose this vote, he had said he would resign leader quickly if he did not get an overwhelming majority. Klein had not publicly divulged what this threshold would be, but most political observers pegged it at 75%, far more than the 55.4% the premier actually received. In previous years, Klein had scored as high as 97% in support of his leadership.
