responsibility for the sponsorship scandal, Justice Gomery ruled that Chrétien was not responsible for the awarding of advertising contracts in Quebec in which millions were stolen, but did accept Charles Guité's claim that he received his instructions on what program to sponsor and to spend how much money on each program from Jean Pelletier, the chief of staff at the PMO between 1993 and 2001 and Jean Carle, the director of operations at the PMO between 1993 and 1998 as the truth. In April 2007, Chrétien and Canadian book publishers Knopf Canada and Éditions du Boréal announced they would be publishing his memoirs, My Years as Prime Minister, which will recount Chrétien's tenure as prime minister.
