Diefenbaker was embittered by his loss of the party leadership. Pearson announced his retirement in December 1967, and Diefenbaker forged a wary relationship of mutual respect with Pearson's successor, Pierre Trudeau. Trudeau called a general election for June 1968; Stanfield asked Diefenbaker to join him at a rally in Saskatoon, which Diefenbaker refused, although the two appeared at hastily arranged photo opportunities. Trudeau obtained the majority against Stanfield that Pearson had never been able to obtain against Diefenbaker, as the PC party lost 25 seats, 20 of them in the West. The former Prime Minister, though stating, "The Conservative Party has suffered a calamitous disaster" in a CBC interview, could not conceal his delight at Stanfield's humiliation, and especially gloated at the defeat of Camp, who made an unsuccessful attempt to enter the Commons. Diefenbaker was easily returned for Prince Albert.
